The spliceosome converts from branching to exon ligation through the ATP-dependent activity of Prp16, a DEAH box helicase8. Prp16 action destabilizes the branching factors Cwc25 and Yju2 (refs 4,9) and creates strong binding sites for the exon ligation factors Slu7 and Prp18 (refs 10,11), while promoting 3′ exon docking7. These factors are essential for splicing of pre-mRNAs with long distances between the branch point and the 3′ splice site12 and for correct 3′ splice site selection13, but their precise roles are unknown. To understand the mechanism of Prp16-mediated spliceosomal remodelling, we assembled spliceosomes in S. cerevisiae extracts on a pre-mRNA substrate containing a deoxy-guanosine at the 3′ splice site UAG sequence and purified them via an affinity-tag on Slu7 (Methods). With this substrate the spliceosomes stall after Prp16-dependent remodelling and before exon ligation, forming the C* complex14; thus purified spliceosomes contain predominantly lariat intermediates (Extended Data Fig. 1). We obtained a cryoEM reconstruction of C* complex at a resolution of 3.8 Å (Extended Data Figs 1, 2), into which we modelled 40 components (Extended Data Tables 1, 2, Extended Data Figs 3, 4 and Supplementary Information). Prp8, Snu114 and the U5 Sm core domain form the foot domain in both C* and C complexes (Fig. 1), which functions as an assembly platform for most of the Prp19 complex (NTC) and Prp19-related (NTR) components including Cwc2, Bud31 and Ecm2. The N-terminal end of Clf1 is anchored by Cef1, Syf2 and the U2/U6 snRNAs exiting the active site (Fig. 1b). The HAT repeats of Clf1 and Syf1 together form a large arch which is rotated considerably in C* relative to the C complex. The N-terminal end of Syf1 interacts with the U2 small nuclear ribonucleoprotein (snRNP), therefore this rotation disrupts the interface between the Prp8 RNase H-like (RH) domain and the U2 snRNP observed in C complex. Consequently, the Prp8 RH domain rotates inward (Extended Data Fig. 5) and the Prp17 WD40 domain moves into the body of the complex. U2 stem IIc swings outwards and no longer interacts with Cwc2/Ecm2 (Extended Data Fig. 5). Unlike in the C complex, no density is visible for Brr2. The RNA structure in the core of the spliceosome remains remarkably unchanged during the C to C* transition, with the exception of the branch helix (Fig. 2a, b). The U2/U6 catalytic triplex adopts the same configuration as in the C complex, consistent with biochemical and genetic evidence15. Density consistent with the presence of Mg2+ ions is observed adjacent to the phosphate oxygen ligands for catalytic metal ions M1 and M2 identified by metal rescue studies (Extended Data Fig. 6), providing further evidence for a single active site for both catalytic steps2. As in the C complex, the 5′ exon is base-paired with loop 1 of U5 snRNA in agreement with genetic analysis and crosslinking experiments16, 17, and the 3′-OH of the last 5′-exon nucleotide (G(−1)) lies close to the M1 site and is ready to act as a nucleophile for the incoming 3′ splice site (Fig. 2c, Extended Data Fig. 6). Prp16-induced remodelling results in a dramatic rotation of the branch helix by approximately 75° around the hinge at A30 of U2 snRNA (Fig. 2b). The branch point moves away from the catalytic centre (approximately 20 Å), creating sufficient space for the 3′ splice site to dock at the catalytic Mg2+ site (Fig. 2a, c). This movement disrupts the non-Watson–Crick interactions of the branch point adenosine (A70) with the branch helix4 and reorganizes the interactions of the 5′ splice site with the U6 snRNA ACAGAGA sequence (Fig. 2d, e). The A70 base is packed against the ribose of the first intron nucleotide G(+1), while the G(+1) base stacks with the base of U(+2). In the C complex, U(+2) forms a base triple with G37 of U2 snRNA and C67 of the intron4, 5 whereas in the C* complex U(+2) forms a non-canonical base-pair with A51 of U6 snRNA (Fig. 2d, e), consistent with crosslinking in human spliceosomes17. Notably, mutations at both U(+2) and A51 impair exon ligation18, 19. Indeed, in group II introns the nucleotide equivalent to A51 (adjacent to the two nucleotides involved in triplex formation) base-pairs with the last nucleotide of the intron (γ–γ′ interaction)20. Thus A51 and intron U(+2) may interact with the last nucleotide G(−1) of the intron. It is noteworthy that all three positions (A70, G(+1), U(+2)/A51), whose mutations lead to second step defects, are aligned towards the active site, strongly suggesting a path for the 3′ splice site (Fig. 2c). Finally, the Hoogsteen base-pair between A(+3) of the intron and G50 of U6 snRNA (Fig. 2e) no longer forms in C* (Fig. 2d), consistent with genetic evidence that this interaction must be disrupted during the Prp16 rearrangement21. The proteins common to both C and C* restrain the catalytic RNA core (U6 snRNA ISL and helices Ia and Ib) onto Prp8, whereas the branch helix rotates substantially between the two states (Fig. 2b). In the C complex, the branch helix is locked into the branching conformation predominantly by Cwc25, Yju2 and Isy1, such that A70 is inserted into the catalytic centre4, 5 (Fig. 3a, b). After branching, Prp16 promotes dissociation of Cwc25, Yju2 and Isy1 and binding of Prp18, Slu7 and Prp22. In the C complex the U2 Sm core domain interacts with the RH domain4, 5 but this interaction is disrupted completely in the C* complex when Prp17 wedges between the U2 Sm ring and the Prp8 RH domain (Fig. 3a, Extended Data Fig. 5). In the C* complex, the RH domain of Prp8 is rotated by about 80° with respect to the large domain (Extended Data Fig. 5d, e). In this orientation, the β-finger of the RH domain crosses the minor groove of the branch helix and reaches Cef1 (Fig. 3a, d). Prp17 binds across the interface between the β-finger and Cef1, stabilizing this interaction. A long α-helix bridges the Prp8 RH domain and the Cef1 Myb domain and reaches the C terminus of Syf1 (Fig. 3c). The direction and sequence of this helix are uncertain from the current map. These interactions lock the branch helix in a conformation predisposed for exon ligation. Prp17 and the rotated position of the RH domain observed in C* would clash with Isy1 and Cwc25, explaining how Prp16-dependent dissociation of Isy1 enables the RH domain to rotate, promoting the exon-ligation configuration. Consistently, deletion of Isy1 suppresses a Prp16 mutation that impairs remodelling of the spliceosome22. The helical domain23 of Prp18 is bound to the Prp8 RH domain opposite from the branch helix binding face (Fig. 3a). Slu7 meanders from the binding site of its predicted globular region towards the foot of the complex, interacts with Prp18, and latches the RH domain onto the endonuclease domain of Prp8, thus stabilizing the rotated conformation of the RH domain and the binding of Prp18 in C* (Extended Data Fig. 7). Indeed, the region of Slu7 that binds the RH domain is essential for yeast viability24. Our C* complex structure provides important insight into the organization of the active site during exon ligation even though the 3′ exon is not yet docked. As discussed above the rotation of the branch helix not only creates a space for the 3′ exon at the catalytic metal binding site but also reorganizes the interaction between the U6 snRNA ACAGAGA sequence and the 5′ end of the intron. An important outcome of Prp16 action is repositioning A51 of U6 snRNA so that it could position the 3′ splice site by interacting with the last nucleotide of the intron like the equivalent nucleotide in group II introns20 (Fig. 2c). If this is the case, it is possible that the penultimate nucleotide A(−2) and its preceding nucleotide Y(−3) may also interact with the first intron nucleotide G(+1) and the branch point adenosine (A70). An interaction between the 3′ splice site UAG sequence, the ACAGAGA sequence and the 5′ splice site intron sequence for exon-ligation has been suggested previously19. However, mutational studies of the 5′ splice site and 3′ splice site have not led to a clear base-pairing scheme19, 25 suggesting that these interactions may involve non-canonical base pairing. The base pairing between the 5′ exon and loop 1 of U5 snRNA (Fig. 2c) places the 3′-OH group of the 5′ exon close to M1 such that it can act as a nucleophile when the phosphate group at the 3′ splice site is bound to M1 and M2 (Extended Data Fig. 6; refs 2,26). Slu7 and Prp18 are dispensable for exon ligation when the distance between the branch point and the 3′ splice site is less than nine nucleotides11. Notably, in our structure, three nucleotides of the intron downstream of the branch point are visible and an additional six nucleotides would be sufficient to fold back and reach the catalytic Mg2+ site (Extended Data Fig. 8; ref. 12). When the distance to the 3′ splice site is less than nine nucleotides, the 3′ splice site could easily reach the catalytic centre and allow the 3′ exon to dock. When the distance is much greater, the entropic cost of docking the 3′ exon would be greater and Slu7 and Prp18 could become indispensable in guiding the path of the intron (Extended Data Fig. 8). Indeed, mutation of Slu7 impairs splicing at distal 3′ splice sites without affecting proximal 3′ splice sites, when two competing sites are present13, 27. The DEAH ATPase Prp22, which promotes exon ligation7, 28, binds on top of the Prp8 large domain (Fig. 4a) near where Prp16 binds in the C complex, consistent with a mutually exclusive interaction with the spliceosome10. Compared to the crystal structure of the homologous Prp43 ATPase in the ADP–Mg-bound form29, Prp22 in our C* complex is in an open conformation with a wider separation of the RecA1 and RecA2 domains (Fig. 4b). Density attributable to RNA is present in the Prp22 active site (Fig. 4b) and Prp22 crosslinks 17 nucleotides downstream of the exon–exon junction6. Indeed, the distance between the catalytic centre of the spliceosome and Prp22 in our structure can be spanned with 16–17 nucleotides. Thus Prp22 could bind to the 3′ exon emerging from the core to promote mRNA release and dissociation of Slu7, Prp18 and Cwc22 after exon ligation. Our C* complex structure elucidates the structural consequences of Prp16 activity (Fig. 4c), reveals a large rotation of the branch helix which creates a space for 3′ exon docking at the catalytic centre in the exon ligation conformation of the spliceosome, and provides a structural framework for investigating 3′ splice site selection and ligated exon release.

« JISEA: nuclear-renewable hybrid energy systems can reduce GHG from industry, produce fuels and support the power system | Main | Honeywell Transportation Systems Forecast: turbocharged vehicles to account for 48% of annual global sales by 2021; electric boosting emerges » Cummins Westport’s ISB6.7 G, a 6.7 liter midrange, factory-built natural gas engine is now fully available as a production engine for shuttle bus, medium duty truck, and vocational applications in North America. (Earlier post.) As previously announced, the engine has been available for school bus applications since May 2016 from Thomas Built Buses. The 6.7 liter engine platform has large OEM availability for midrange trucks, vocational trucks and mid size buses and the expansion of applications potentially available for the ISB6.7 G engine more than doubles its addressable market. The ISB6.7 G is based on the Cummins ISB6.7 diesel engine platform, the industry leader in the Cummins midrange engine family, and operates exclusively on natural gas, including compressed, liquid, or renewable natural gas (RNG). The ISB6.7 G is the second engine from Cummins Westport (CWI) to receive emission certification from the US Environmental Protection Agency (EPA) and the Air Resources Board (ARB) in California for meeting the Optional Low NO Emissions standards. An engine of this size is a natural addition to CWI’s portfolio of natural gas engines. Many customers using school and shuttle buses, medium duty trucks, or vocational vehicles operate within a local area where the return to base nature of their operation allows them to use fleet-owned or growing publicly available natural gas fueling infrastructure. The ISB6.7 G offers the midrange customer an ability to take advantage of the most cost effective overall solution with the benefit of a low emission natural gas engine that has proven performance, reliability, and durability. In addition, operating on RNG offers customers a tremendous greenhouse gas savings opportunity versus fossil fuels. The ISB6.7 G features the same advanced combustion controls with Three-Way Catalyst (TWC) as Cummins Westport’s ISL G & ISX12 G engines. NO emissions of the ISB6.7 G are 0.1 g/bhp-hr—50% lower than the current EPA and ARB NO limit of 0.2 g/bhp-hr. CO emissions meet the 2017 EPA greenhouse gas (GHG) emission requirements. All CWI natural gas engines are lower than the 2010 EPA standard for particulate matter (0.01 g/bhp-hr). The ISB6.7 G utilizes CWI proprietary spark-ignited, stoichiometric combustion with cooled exhaust gas recirculation (SEGR) technology. It features electronic control with programmable features, a closed crankcase ventilation system, and maintenance-free three-way catalyst aftertreatment. No diesel particulate filter or selective catalytic reduction aftertreatment is required. The SEGR technology was introduced with the ISL G in 2007, and was developed to meet 2010 EPA emission requirements. The cooled-EGR system passes exhaust gas through a cooler to reduce temperatures before mixing it with fuel and the incoming air charge to the cylinder. Stoichiometric combustion in combination with cooled-EGR offers increased power density and thermal efficiency. It also reduces in-cylinder combustion temperatures and creates an oxygen-free exhaust, which then enables the use of a three-way catalyst (TWC) for NO control. The ISB6.7 G will be manufactured in the Cummins engine plant and offered in three ratings up to 240 hp (179 kW) and 560 lb-ft (759 N·m) torque. Power Take-Off and automatic transmission capability meet customer and original equipment manufacturer requirements. Base warranty is two years, with unlimited miles/kilometers. Extended Coverage options are also available. Partial funding in support of the ISB6.7 G engine development has been received from the California Energy Commission through its Public Interest Energy Research (PIER) Program in conjunction with the Gas Technology Institute.

« Dahn team develops ethylene-carbonate-free electrolytes for better-performing high-voltage Li-ion cells | Main | New Flyer adds 2016 Cummins Westport ISL G Near Zero engine to Xcelsior bus lineup; debuting in LA » The Institute for Advanced Composites Manufacturing Innovation, IACMI, in partnership with DuPont Performance Materials, Fibrtec Inc. and Purdue University, has launched the first project selected with a dual focus on decreasing the cost of manufacture and increasing design flexibility for automotive composites. Advancements in both areas can open up new opportunities and become an enabler for large-scale deployment of composite parts. Multiple factors, including cost and design constraints, present barriers to the adoption of composites in high volume automotive applications. This new IACMI project will address both of these critical areas through a fundamentally different approach to the manufacturing of carbon fiber composites versus those currently in use today. The work will build on synergies of differentiated technologies, including novel materials and processes that allow flexible pre-pregs (Fiberflex) combined with Rapid Fabric Formation (RFF) technology to provide customizable fiber orientations via thermal bonding to significantly improve cycle time, cost, and waste. The final component will benefit from increased production speeds of the tow manufacturing process and the fabric forming process resulting in a lower cost of manufacture. The partners have estimated that use of emerging materials for impregnation and new approaches for tow coating and fabric formation will lower costs of high volume composites production by 20%. Composite parts made by this process have been shown to have low voids and good mechanical properties when consolidated by traditional techniques. The flexible fabric prepregs have also been shown to have good draping behavior in molding experiments. Researchers in the Purdue University Composites Manufacturing and Simulation Center will work with the team to model and validate drapability and part performance. High cycle time for production of continuous carbon fiber thermoplastic composites increases costs. The use of emerging materials for impregnation and new approaches for tow coating and fabric formation are expected to significantly lower production costs of high volume composites. The Institute for Advanced Composites Manufacturing Innovation (IACMI), managed by the Collaborative Composite Solutions Corporation (CCS), is a partnership of industry, universities, national laboratories, and federal, state and local governments working together to accelerate development and commercial deployment of advanced composites. CCS is a not-for-profit organization established by The University of Tennessee Research Foundation. The national institute is supported by a $70-million commitment from the US Department of Energy’s Advanced Manufacturing Office and more than $180 million committed from IACMI’s partners.

« New Flyer adds 2016 Cummins Westport ISL G Near Zero engine to Xcelsior bus lineup; debuting in LA | Main | FEV North America, Inc. opening office in Silicon Valley » Energy-associated CO emissions from natural gas are expected to surpass those from coal for the first time since 1972, according to the US Energy Information Administration (EIA). Even though natural gas is less carbon-intensive than coal, increases in natural gas consumption and decreases in coal consumption in the past decade have resulted in natural gas-related CO emissions surpassing those from coal. EIA’s latest Short-Term Energy Outlook projects energy-related CO emissions from natural gas to be 10% greater than those from coal in 2016. From 1990 to about 2005, consumption of coal and natural gas in the United States was relatively similar, but their emissions were different; coal is more carbon-intensive than natural gas. The consumption of natural gas results in about 52 million metric tons of CO for every quadrillion British thermal units (MMmtCO /quad Btu), while coal’s carbon intensity is about 95 MMmtCO /quad Btu, or about 82% higher than natural gas’s carbon intensity. Because coal has a higher carbon intensity, even in a year when consumption of coal and natural gas were nearly equal, such as 2005, energy-related CO emissions from coal were about 84% higher than those from natural gas. In 2015, natural gas consumption was 81% higher than coal consumption, and their emissions were nearly equal. Both fuels were associated with about 1.5 billion metric tons of energy-related CO emissions in the United States in 2015.

« IACMI, DuPont and Purdue partner on automotive carbon-fiber composites | Main | EIA: energy-related CO2 emissions from natural gas surpass coal as fuel use patterns change » Flyer of America Inc., a subsidiary of New Flyer Industries Inc., the largest heavy-duty transit bus and motor coach manufacturer and parts distributor in North America, is adding the 2016 Cummins Westport ISL G Near Zero engine (earlier post) to its Xcelsior bus family. New Flyer is the first transit manufacturer to offer the industry’s cleanest certified engine and will deliver the first original OEM installation of a the engine in the third quarter of 2016. The ISL G NZ compressed natural gas is certified by both US Environmental Protection Agency (EPA) and Air Resources Board (ARB) in California to meet the 0.02 g/bhp-hr optional Near Zero NO Emissions standards for medium-duty truck, urban bus, school bus and refuse applications. The engine will be used to power a New Flyer Xcelsior XN40 bus for the Los Angeles County Metropolitan Transportation Authority (LA Metro). LA Metro operates the largest natural gas engine transit vehicle fleet in North America. Cummins Westport states that this certification represents a 10-fold emissions reduction below current EPA NO emissions standards, making it the cleanest engine in the industry. Cummins Westport also describes the engine as operating 90% below the particulate matter (PM) standard, and 16% below the CO emissions standard. In addition to the significant reduction in NO , the ISL G NZ features Closed Crankcase Ventilation, stated to reduce engine related methane emissions by 70%, thereby enhancing its greenhouse gas benefits. The ISL G NZ is built off the current ISL G platform, but requires Closed Crankcase Ventilation (CCV); a larger maintenance-free Three-Way Catalyst (TWC); and a unique engine calibration. Performance and efficiency match the current ISL G, with engine ratings from 250-320 horsepower, and 660-1,000 lb-ft torque available. Base warranty, extended coverage options, maintenance procedures and service intervals are also the same as the current ISL G. The new engine has similar emission control systems (throttle body injection, TWC, EGR, etc.) as the 0.20 g/bhp-hr NO ISL G. We are proud to be the first OEM to factory install and deliver this industry-leading clean engine to a transit customer. New Flyer has delivered over 6,000 natural gas transit buses that operate to ranges of over 350 miles without refueling. The advancements of Cummins Westport in compressed natural gas internal combustion and after-treatment technology has helped our customers meet stringent clean air requirements, powered by low cost natural gas. Paul Smith, New Flyer’s Executive Vice President, Sales and Marketing, also noted the growing customer interest in renewable natural gas (RNG), also known as biomethane. RNG is chemically identical to fossil natural gas, and yields far fewer greenhouse emissions during the production process. RNG is a pipeline-quality gas that's fully interchangeable with conventional natural gas, yet can be produced by reusing waste products. It can be produced from landfills, livestock operations and wastewater treatment. Combining this renewable energy source with the Cummins Westport ISL G NZ engine provides a powerful tool to significantly improve urban air quality, while, at the same time, also reducing greenhouse gas emissions. Transit agencies now have more clean air, low greenhouse gas options than ever from New Flyer and can select from an array of propulsion systems that collectively meets their operational needs, all of which are available on the lightweight, industry proven, and reliable Xcelsior platform.
