CC -!- FUNCTION: Produces ATP from ADP in the presence of a proton gradient
CC across the membrane. The alpha chain is a regulatory subunit.
CC {ECO:0000255|HAMAP-Rule:MF_01346}.
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:0000255|HAMAP-Rule:MF_01346};
CC -!- SUBUNIT: F-type ATPases have 2 components, CF(1) - the catalytic core
CC - and CF(0) - the membrane proton channel. CF(1) has five subunits:
CC alpha(3), beta(3), gamma(1), delta(1), epsilon(1). CF(0) has three main
CC subunits: a(1), b(2) and c(9-12). The alpha and beta chains form an
CC alternating ring which encloses part of the gamma chain. CF(1) is
CC attached to CF(0) by a central stalk formed by the gamma and epsilon
CC chains, while a peripheral stalk is formed by the delta and b chains.
CC {ECO:0000255|HAMAP-Rule:MF_01346}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC Rule:MF_01346}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC Rule:MF_01346}.
CC -!- SIMILARITY: Belongs to the ATPase alpha/beta chains family.
CC {ECO:0000255|HAMAP-Rule:MF_01346}.
