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 (Probable). Minor
CC subunit required to maintain the ATP synthase population in the
CC mitochondria (PubMed:24330338). {ECO:0000269|PubMed:24330338,
CC ECO:0000305}.
CC -!- SUBUNIT: Component of an ATP synthase complex composed of ATP5PB,
CC ATP5MC1, ATP5F1E, ATP5PD, ATP5ME, ATP5PF, ATP5MF, MT-ATP6, MT-ATP8,
CC ATP5F1A, ATP5F1B, ATP5F1D, ATP5F1C, ATP5PO, ATP5MG, ATP5MK and ATP5MJ.
