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. Part of the complex
CC       F(0) domain. A homomeric c-ring of probably 10 subunits is part of the
CC       complex rotary element.
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.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion membrane {ECO:0000305}; Multi-pass
CC       membrane protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the ATPase C chain family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAT64949.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
