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}.
