CC -!- FUNCTION: Mitochondrial membrane ATP synthase (F(1)F(0) ATP CC synthase or Complex V) produces ATP from ADP in the presence of a CC proton gradient across the membrane which is generated by electron CC transport complexes of the respiratory chain. F-type ATPases CC consist of two structural domains, F(1) - containing the CC extramembraneous catalytic core and F(0) - containing the membrane CC proton channel, linked together by a central stalk and a CC peripheral stalk. During catalysis, ATP synthesis in the catalytic CC domain of F(1) is coupled via a rotary mechanism of the central CC 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 CC core - and CF(0) - the membrane proton channel. CF(1) has five CC subunits: alpha(3), beta(3), gamma(1), delta(1), epsilon(1). CF(0) CC has three main subunits: a, b and c. CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane; Multi-pass CC membrane protein. CC -!- SIMILARITY: Belongs to the ATPase A chain family.
