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.
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. Component of an ATP synthase complex composed of
CC       ATP5PB, ATP5MC1, ATP5F1E, ATP5PD, ATP5ME, ATP5PF, ATP5MF, MT-ATP6, MT-
CC       ATP8, ATP5F1A, ATP5F1B, ATP5F1D, ATP5F1C, ATP5PO, ATP5MG, ATP5MK and
CC       ATP5MJ (By similarity). Interacts with DNAJC30; interaction is direct
CC       (By similarity). {ECO:0000250|UniProtKB:P00846,
CC       ECO:0000250|UniProtKB:P00847}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane; Multi-pass membrane
CC       protein.
CC   -!- SIMILARITY: Belongs to the ATPase A chain family. {ECO:0000305}.
