'''THE STRUCTURE OF BOVINE F1-ATPASE COVALENTLY INHIBITED WITH 4-CHLORO-7-NITROBENZOFURAZAN'''<br />


==Overview==
==THE STRUCTURE OF BOVINE F1-ATPASE COVALENTLY INHIBITED WITH 4-CHLORO-7-NITROBENZOFURAZAN==
BACKGROUND: F1-ATPase is the globular domain of F1F0-ATP synthase that, catalyses the hydrolysis of ATP to ADP and phosphate. The crystal, structure of bovine F1-ATPase has been determined previously to 2.8 A, resolution. The enzyme comprises five different subunits in the, stoichiometry alpha 3 beta 3 gamma delta epsilon; the three catalytic beta, subunits alternate with the three alpha subunits around the centrally, located single gamma subunit. To understand more about the catalytic, mechanisms, F1-ATPase was inhibited by reaction with, 4-chloro-7-nitrobenzofurazan (NBD-Cl) and the structure of the inhibited, complex (F1-NBD) determined by X-ray crystallography. RESULTS: In the, structure the three beta subunits adopt a different conformation with, different nucleotide occupancy. ... [[http://ispc.weizmann.ac.il/pmbin/getpm?9687365 (full description)]]

Function

ATPA_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).
