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 three main
CC       subunits: a(1), b(2) and c(9-12). The alpha and beta chains form an
CC       alternating ring which encloses part of the gamma chain. CF(1) is
CC       attached to CF(0) by a central stalk formed by the gamma and epsilon
CC       chains, while a peripheral stalk is formed by the delta and b chains.
CC       {ECO:0000255|HAMAP-Rule:MF_01393}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01393}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01393}.
CC   -!- SIMILARITY: Belongs to the ATPase A chain family. {ECO:0000255|HAMAP-
CC       Rule:MF_01393}.
