CC -!- FUNCTION: Key component of the proton channel; it plays a direct role CC in the translocation of protons across the membrane. CC {ECO:0000256|HAMAP-Rule:MF_01393}. 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, b, b' and c. {ECO:0000256|HAMAP-Rule:MF_01393}. CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000256|ARBA:ARBA00004141}; Multi- CC pass membrane protein {ECO:0000256|ARBA:ARBA00004141}. Plastid, CC chloroplast thylakoid membrane {ECO:0000256|HAMAP-Rule:MF_01393, CC ECO:0000256|RuleBase:RU004449}; Multi-pass membrane protein CC {ECO:0000256|HAMAP-Rule:MF_01393, ECO:0000256|RuleBase:RU004449}. CC -!- SIMILARITY: Belongs to the ATPase A chain family. CC {ECO:0000256|ARBA:ARBA00006810, ECO:0000256|HAMAP-Rule:MF_01393}.
