1NBM - PubMed Abstract: 
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.
