Method: Electron Microscopy, Resolution 7Å Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function VPP1_YEAST Subunit of the V0 complex of vacuolar(H+)-ATPase (V-ATPase), a multisubunit enzyme composed of a peripheral complex (V1) that hydrolyzes ATP and a membrane integral complex (V0) that translocates protons (PubMed:1491220, PubMed:8798414, PubMed:11278748). V-ATPase is responsible for acidifying and maintaining the pH of intracellular compartments (PubMed:1491220, PubMed:11278748). Is present only in vacuolar V-ATPase complexes; enzymes containing this subunit have a 4-fold higher ratio of proton transport to ATP hydrolysis than complexes containing the Golgi/endosomal isoform and undergo reversible dissociation of V1 and V0 in response to glucose depletion (PubMed:8798414, PubMed:11278748).
