Biol. Chem. 261:11680-11685(1986). 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}.
