CC -!- FUNCTION: Produces ATP from ADP in the presence of a proton gradient
CC across the membrane. {ECO:0000256|HAMAP-Rule:MF_00530}.
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, b and c. {ECO:0000256|HAMAP-Rule:MF_00530,
CC ECO:0000256|RuleBase:RU003656}.
CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane
CC {ECO:0000256|ARBA:ARBA00004142, ECO:0000256|HAMAP-Rule:MF_00530};
CC Peripheral membrane protein {ECO:0000256|ARBA:ARBA00004142,
CC ECO:0000256|HAMAP-Rule:MF_00530}. Membrane
CC {ECO:0000256|ARBA:ARBA00004170}; Peripheral membrane protein
CC {ECO:0000256|ARBA:ARBA00004170}.
CC -!- SIMILARITY: Belongs to the ATPase epsilon chain family.
CC {ECO:0000256|ARBA:ARBA00005712, ECO:0000256|HAMAP-Rule:MF_00530,
CC ECO:0000256|RuleBase:RU003656}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
