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
CC       F(0) - containing the membrane proton channel, linked together by a
CC       central stalk and a peripheral stalk. During catalysis, ATP synthesis
CC       in the catalytic domain of F(1) is coupled via a rotary mechanism of
CC       the central stalk subunits to proton translocation. Part of the complex
CC       F(0) domain and the peripheric stalk, which acts as a stator to hold
CC       the catalytic alpha(3)beta(3) subcomplex and subunit a/ATP6 static
CC       relative to the rotary elements.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion. Mitochondrion inner membrane.
CC   -!- SIMILARITY: Belongs to the eukaryotic ATPase B chain family.
CC       {ECO:0000305}.
