--- _id: '8581' abstract: - lang: eng text: The majority of adenosine triphosphate (ATP) powering cellular processes in eukaryotes is produced by the mitochondrial F1Fo ATP synthase. Here, we present the atomic models of the membrane Fo domain and the entire mammalian (ovine) F1Fo, determined by cryo-electron microscopy. Subunits in the membrane domain are arranged in the ‘proton translocation cluster’ attached to the c-ring and a more distant ‘hook apparatus’ holding subunit e. Unexpectedly, this subunit is anchored to a lipid ‘plug’ capping the c-ring. We present a detailed proton translocation pathway in mammalian Fo and key inter-monomer contacts in F1Fo multimers. Cryo-EM maps of F1Fo exposed to calcium reveal a retracted subunit e and a disassembled c-ring, suggesting permeability transition pore opening. We propose a model for the permeability transition pore opening, whereby subunit e pulls the lipid plug out of the c-ring. Our structure will allow the design of drugs for many emerging applications in medicine. acknowledged_ssus: - _id: EM-Fac - _id: ScienComp acknowledgement: We thank J.

They belong to the V-typeATPase family, which differs from the mitochondrial/chloroplast F-type ATP synthasesin overall architecture. We solved cryo–electron microscopy structures of the intactThermus thermophilusV/A-ATPase, reconstituted into lipid nanodiscs, in three rotationalstates and two substates. These structures indicate substantial flexibility betweenV1and Voin a working enzyme, which results from mechanical competition between centralshaft rotation and resistance from the peripheral stalks. We also describedetails of adenosine diphosphate inhibition release, V1-Votorque transmission, andproton translocation, which are relevant for the entire V-type ATPase family. acknowledged_ssus: - _id: ScienComp article_number: eaaw9144 article_processing_charge: No author: - first_name: Long full_name: Zhou, Long id: 3E751364-F248-11E8-B48F-1D18A9856A87 last_name: Zhou orcid: 0000-0002-1864-8951 - first_name: Leonid A full_name: Sazanov, Leonid A id: 338D39FE-F248-11E8-B48F-1D18A9856A87 last_name: Sazanov orcid: 0000-0002-0977-7989 citation: ama: Zhou L, Sazanov LA.

The crystal structure of the OSCAR ectodomain is presented, both free and in complex with a consensus triple-helical peptide (THP). The structures revealed a collagen-binding site in each immunoglobulin-like domain (D1 and D2). The THP binds near a predicted collagen-binding groove in D1, but a more extensive interaction with D2 is facilitated by the unusually wide D1-D2 interdomain angle in OSCAR. Direct binding assays, combined with site-directed mutagenesis, confirm that the primary collagen-binding site in OSCAR resides in D2, in marked contrast to the related collagen receptors, glycoprotein VI (GPVI) and leukocyte-associated immunoglobulin-like receptor-1 (LAIR-1). Monomeric OSCAR D1D2 binds to the consensus THP with a KD of 28 µM measured in solution, but shows a higher affinity (KD 1.5 μM) when binding to a solid-phase THP, most likely due to an avidity effect. These data suggest a 2-stage model for the interaction of OSCAR with a collagen fibril, with transient, low-affinity interactions initiated by the membrane-distal D1, followed by firm adhesion to the primary binding site in D2. author: - first_name: Long full_name: Zhou, Long id: 3E751364-F248-11E8-B48F-1D18A9856A87 last_name: Zhou orcid: 0000-0002-1864-8951 - first_name: J.
