![]() | ![]() タイトル: Structure of yeast RAVE bound to a partial V complex. 著者: Hanlin Wang / Maureen Tarsio / Patricia M Kane / John L Rubinstein / ![]() ![]() 要旨: Vacuolar-type ATPases (V-ATPases) are membrane-embedded proton pumps that acidify intracellular compartments in almost all eukaryotic cells. Homologous with ATP synthases, these multisubunit enzymes ...Vacuolar-type ATPases (V-ATPases) are membrane-embedded proton pumps that acidify intracellular compartments in almost all eukaryotic cells. Homologous with ATP synthases, these multisubunit enzymes consist of a soluble catalytic V subcomplex and a membrane-embedded proton-translocating V subcomplex. The V and V subcomplexes can undergo reversible dissociation to regulate proton pumping, with reassociation of V and V requiring the protein complex known as RAVE (regulator of the ATPase of vacuoles and endosomes). In the yeast , RAVE consists of subunits Rav1p, Rav2p, and Skp1p. We used electron cryomicroscopy (cryo-EM) to determine a structure of yeast RAVE bound to V. In the structure, RAVE is an L-shaped complex with Rav2p pointing toward the membrane and Skp1p distant from both the membrane and V. Only Rav1p interacts with V, binding to a region of subunit A not found in the corresponding ATP synthase subunit. When bound to RAVE, V is in a rotational state suitable for binding the free V complex, but in the structure, it is partially disrupted, missing five of its 16 subunits. Other than these missing subunits and the conformation of the inhibitory subunit H, the V complex with RAVE appears poised for reassembly with V. | ||||||||||||||||||||||||||||||||||||
