CC -!- FUNCTION: Catalytic subunit of the peripheral V1 complex of vacuolar
CC ATPase. V-ATPase vacuolar ATPase is responsible for acidifying a
CC variety of intracellular compartments in eukaryotic cells.
CC {ECO:0000256|ARBA:ARBA00003685}.
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:0000256|ARBA:ARBA00001741};
CC -!- SIMILARITY: Belongs to the ATPase alpha/beta chains family.
CC {ECO:0000256|ARBA:ARBA00008936}.
