CC -!- FUNCTION: Produces ATP from ADP in the presence of a proton gradient
CC across the membrane. The catalytic sites are hosted primarily by the
CC beta subunits. {ECO:0000255|HAMAP-Rule:MF_01347}.
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_01347};
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 four main
CC subunits: a(1), b(1), b'(1) and c(9-12). {ECO:0000255|HAMAP-
CC Rule:MF_01347}.
CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane {ECO:0000255|HAMAP-
CC Rule:MF_01347}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC Rule:MF_01347}.
CC -!- SIMILARITY: Belongs to the ATPase alpha/beta chains family.
CC {ECO:0000255|HAMAP-Rule:MF_01347}.
