CC   -!- FUNCTION: Produces ATP from ADP in the presence of a proton gradient
CC       across the membrane.
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:0000269|PubMed:2872924}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Peripheral membrane
CC       protein {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the ATPase epsilon chain family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=BAA96810.1; Type=Frameshift; Evidence={ECO:0000305};
