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).
