THE STRUCTURE OF BOVINE F1-ATPASE COVALENTLY INHIBITED WITH 4-CHLORO-7-NITROBENZOFURAZAN

Overview

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. ... [(full description)]
