. "A multisubunit non-phosphorylated ATPase that is involved in the transport of ions." . "Large enzymes of mitochondria, chloroplasts and bacteria with a membrane sector (F(o), V(o), A(o)) and a cytoplasmic-compartment sector (F(1), V(1), A(1))." . "The F-type enzymes of the inner mitochondrial and thylakoid membranes act as ATP synthases." . "All of the enzymes included here operate in a rotational mode, where the extramembrane sector (containing 3 alpha-and 3 beta-subunits) is connected via the delta-subunit to the membrane sector by several smaller subunits." . "Within this complex, the gamma-and epsilon-subunits, as well as the 9-12 c subunits rotate by consecutive 120 degree angles and perform parts of ATP synthesis." . "This movement is driven by the H(+) electrochemical potential gradient." . "The V-type (in vacuoles and clathrin-coated vesicles) and A-type (archaeal) enzymes have a similar structure but, under physiological conditions, they pump H(+) rather than synthesize ATP." . . .
