CC -!- FUNCTION: Key component of the proton channel; it plays a direct role
CC 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 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:0000255|HAMAP-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}.
CC -!- SIMILARITY: Belongs to the ATPase A chain family. {ECO:0000255|HAMAP-
CC Rule:MF_01393}.
