DESCRIPTION

Also known as ATP6_YEAST, ATP6, OLI2, OLI4, PHO1. 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 transport complexes of the respiratory chain. F-type ATPases consist of two structural domains, F(1) - containing the extramembraneous catalytic core and F(0) - containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. During catalysis, ATP synthesis in the catalytic domain of F(1) is coupled via a rotary mechanism of the central stalk subunits to proton translocation. Key component of the proton channel; it may play a direct role in the translocation of protons across the membrane. F-type ATPases have 2 components, CF(1) - the catalytic core - and CF(0) - the membrane proton channel. In yeast, the dimeric form of ATP synthase consists of 17 polypeptides: alpha, beta, gamma, delta, epsilon, 4 (B), 5 (OSCP), 6 (A), 8, 9 (C), d, E (Tim11), f, g, h, i/j and k.
