CC   -!- FUNCTION: F(1)F(0) ATP synthase produces ATP from ADP in the presence
CC       of a proton or sodium gradient. F-type ATPases consist of two
CC       structural domains, F(1) containing the extramembraneous catalytic core
CC       and F(0) containing the membrane proton channel, linked together by a
CC       central stalk and a peripheral stalk. During catalysis, ATP synthesis
CC       in the catalytic domain of F(1) is coupled via a rotary mechanism of
CC       the central stalk subunits to proton translocation. {ECO:0000255|HAMAP-
CC       Rule:MF_01398}.
CC   -!- FUNCTION: Component of the F(0) channel, it forms part of the
CC       peripheral stalk, linking F(1) to F(0). {ECO:0000255|HAMAP-
CC       Rule:MF_01398}.
CC   -!- SUBUNIT: F-type ATPases have 2 components, F(1) - the catalytic core
CC       - and F(0) - the membrane proton channel. F(1) has five subunits:
CC       alpha(3), beta(3), gamma(1), delta(1), epsilon(1). F(0) has three main
CC       subunits: a(1), b(2) and c(10-14). The alpha and beta chains form an
CC       alternating ring which encloses part of the gamma chain. F(1) is
CC       attached to F(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_01398}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01398}; Single-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01398}.
CC   -!- SIMILARITY: Belongs to the ATPase B chain family. {ECO:0000255|HAMAP-
CC       Rule:MF_01398}.
