 Citation |  Journal: Nat Struct Mol Biol / Year: 2022Title: Coordinated conformational changes in the V complex during V-ATPase reversible dissociation. Authors: Thamiya Vasanthakumar / Kristine A Keon / Stephanie A Bueler / Michael C Jaskolka / John L Rubinstein /   ![]() Abstract: Vacuolar-type ATPases (V-ATPases) are rotary enzymes that acidify intracellular compartments in eukaryotic cells. These multi-subunit complexes consist of a cytoplasmic V region that hydrolyzes ATP ...Vacuolar-type ATPases (V-ATPases) are rotary enzymes that acidify intracellular compartments in eukaryotic cells. These multi-subunit complexes consist of a cytoplasmic V region that hydrolyzes ATP and a membrane-embedded V region that transports protons. V-ATPase activity is regulated by reversible dissociation of the two regions, with the isolated V and V complexes becoming autoinhibited on disassembly and subunit C subsequently detaching from V. In yeast, assembly of the V and V regions is mediated by the regulator of the ATPase of vacuoles and endosomes (RAVE) complex through an unknown mechanism. We used cryogenic-electron microscopy of yeast V-ATPase to determine structures of the intact enzyme, the dissociated but complete V complex and the V complex lacking subunit C. On separation, V undergoes a dramatic conformational rearrangement, with its rotational state becoming incompatible for reassembly with V. Loss of subunit C allows V to match the rotational state of V, suggesting how RAVE could reassemble V and V by recruiting subunit C.  | |||||||||
