CC -!- FUNCTION: Key component of the proton channel; it plays a direct CC role in the translocation of protons across the membrane. CC {ECO:0000255|HAMAP-Rule:MF_01393}. CC -!- SUBUNIT: F-type ATPases have 2 components, CF(1) - the catalytic CC core - and CF(0) - the membrane proton channel. CF(1) has five CC subunits: alpha(3), beta(3), gamma(1), delta(1), epsilon(1). CF(0) CC has four main subunits: a, b, b' and c. {ECO:0000255|HAMAP- CC Rule:MF_01393}. CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane CC {ECO:0000255|HAMAP-Rule:MF_01393}; Multi-pass membrane protein CC {ECO:0000255|HAMAP-Rule:MF_01393}.
