CC   -!- FUNCTION: Produces ATP from ADP in the presence of a proton gradient
CC       across the membrane. {ECO:0000255|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.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255|HAMAP-Rule:MF_00530};
CC       Peripheral membrane protein {ECO:0000255|HAMAP-Rule:MF_00530}.
CC   -!- SIMILARITY: Belongs to the ATPase epsilon chain family.
CC       {ECO:0000255|HAMAP-Rule:MF_00530}.
