Function

ATPA_YEAST 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. Subunits alpha and beta form the catalytic core in F(1). Rotation of the central stalk against the surrounding alpha(3)beta(3) subunits leads to hydrolysis of ATP in three separate catalytic sites on the beta subunits. Subunit alpha does not bear the catalytic high-affinity ATP-binding sites (By similarity).

Publication Abstract from PubMed

The F(1)F(O)-ATP synthase is a rotary molecular nanomotor. F(1) is a chemical motor driven by ATP hydrolysis while F(O) is an electrical motor driven by the proton flow. The two stepping motors are mechanically coupled through a common rotary shaft. Up to now, the three available crystal structures of the F(1)c(10) sub-complex of the yeast F(1)F(O)-ATP synthase were isomorphous and then named yF(1)c(10)(I). In this crystal form, significant interactions of the c(10)-ring with the F(1)-head of neighboring molecules affected the overall conformation of the F(1)-c-ring complex. The symmetry axis of the F(1)-head and the inertia axis of the c-ring were tilted near the interface between the F(1)-central stalk and the c-ring rotor, resulting in an unbalanced machine. We have solved a new crystal form of the F(1)c(10) complex, named yF(1)c(10)(II), inhibited by adenylyl-imidodiphosphate (AMP-PNP) and dicyclohexylcarbodiimide (DCCD), at 6.5A resolution in which the crystal packing has a weaker influence over the conformation of the F(1)-c-ring complex. yF(1)c(10)(II) provides a model of a more efficient generator. yF(1)c(10)(II) and bovine bF(1)c(8) structures share a common rotor architecture with the inertia center of the F(1)-stator close to the rotor axis.
