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. Minor subunit located with subunit a in the membrane (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBUNIT: F-type ATPases have 2 components, CF(1) - the catalytic core
CC       - and CF(0) - the membrane proton channel. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion membrane; Single-pass membrane
CC       protein.
CC   -!- SIMILARITY: Belongs to the ATPase protein 8 family. {ECO:0000305}.
