FunctionATPA_BOVIN 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). Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedAnalysis of tryptophan mutants of F(1)-ATPase from Escherichia coli [Lobau et al. (1997) FEBS Lett. 404, 15-18] suggested that nucleotide concentrations used to grow crystals for the determination of the structure of bovine F(1)-ATPase [Abrahams et al. (1994) Nature 370, 621-628] would be sufficient to occupy only two catalytic sites, and that higher concentrations of nucleotide would result in all three sites being occupied. We have determined the structure of bovine F(1)-ATPase at 2.9 A resolution with crystals grown in the presence of 5 mM AMPPNP and 5 microM ADP. Similar to previous structures of bovine F(1)-ATPase determined with crystals grown in the presence of lower nucleotide concentrations, only two beta-subunits have bound nucleotide and the third subunit remains empty. The structure and nucleotide occupancy of bovine mitochondrial F(1)-ATPase are not influenced by crystallisation at high concentrations of nucleotide.,Menz RI, Leslie AG, Walker JE FEBS Lett. 2001 Apr 6;494(1-2):11-4.
