CC -!- FUNCTION: Mitochondrial membrane ATP synthase (F(1)F(0) ATP synthase or
CC Complex V) produces ATP from ADP in the presence of a proton gradient
CC across the membrane which is generated by electron transport complexes
CC of the respiratory chain. F-type ATPases consist of two structural
CC domains, F(1) - containing the extramembraneous catalytic core and F(0)
CC - containing the membrane proton channel, linked together by a central
CC stalk and a peripheral stalk. During catalysis, ATP synthesis in the
CC catalytic domain of F(1) is coupled via a rotary mechanism of the
CC central stalk subunits to proton translocation. Key component of the
CC proton channel; it may play a direct role in the translocation of
CC protons across the membrane (By similarity). {ECO:0000250}.
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, b and c (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane; Multi-pass membrane
CC protein.
CC -!- SIMILARITY: Belongs to the ATPase A chain family. {ECO:0000305}.
