CC -!- FUNCTION: Catalytic subunit of the V1 complex of vacuolar(H+)-ATPase
CC (V-ATPase), a multisubunit enzyme composed of a peripheral complex (V1)
CC that hydrolyzes ATP and a membrane integral complex (V0) that
CC translocates protons (By similarity). V-ATPase is responsible for
CC acidifying and maintaining the pH of intracellular compartments and in
CC some cell types, is targeted to the plasma membrane, where it is
CC responsible for acidifying the extracellular environment (By
CC similarity). {ECO:0000250|UniProtKB:P38606,
CC ECO:0000250|UniProtKB:P50516}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + 4 H(+)(in) + H2O = ADP + 5 H(+)(out) + phosphate;
CC Xref=Rhea:RHEA:57720, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=7.1.2.2;
CC Evidence={ECO:0000250|UniProtKB:P50516};
CC -!- ACTIVITY REGULATION: ATP hydrolysis occurs at the interface between the
CC nucleotide-binding domains of subunits A and B (By similarity). ATP
CC hydrolysis triggers a conformational change in the subunits D and F,
CC which induces a shift of subunit d (By similarity). The c-ring is
CC subsequently rotated and results in a continuous proton translocation
CC across the membrane (By similarity). {ECO:0000250|UniProtKB:P31404}.
CC -!- SUBUNIT: V-ATPase is a heteromultimeric enzyme made up of two
CC complexes: the ATP-hydrolytic V1 complex and the proton translocation
CC V0 complex (By similarity). The V1 complex consists of three catalytic
CC AB heterodimers that form a heterohexamer, three peripheral stalks each
CC consisting of EG heterodimers, one central rotor including subunits D
CC and F, and the regulatory subunits C and H (By similarity). The proton
CC translocation complex V0 consists of the proton transport subunit a, a
CC ring of proteolipid subunits c9c'', rotary subunit d, subunits e and f,
CC and the accessory subunits VhaAC45 and ATP6AP2 (By similarity).
CC {ECO:0000250|UniProtKB:P38606}.
CC -!- SIMILARITY: Belongs to the ATPase alpha/beta chains family.
CC {ECO:0000305}.
