ATP synthase protein 8 (MT-ATP8)

Mitochondrial membrane ATP synthase (F(1)F(0) ATP synthase or Complex V) produces ATP from ADP in the presence of a proton gradient across the membrane which is generated by electron transfer complexes of the respiratory chain. F-type ATPases consist of two structural domains, F(1) - comprising the extramembraneous catalytic core and F(0) - comprising the membrane proton channel, linked together by a central stalk and a peripheral stem.

During catalysis, ATP synthesis in the catalytic domain of F(1) is coupled by means of a rotary mechanism of the central stalk subunits to proton translocation. Part of the complex F(0) domain.
