Crystallographic Investigation of Inhibition Mode of the VIM-2 Metallo-beta-lactamase from Pseudomonas aeruginosa with Mercaptocarboxylate InhibitorCrystallographic Investigation of Inhibition Mode of the VIM-2 Metallo-beta-lactamase from Pseudomonas aeruginosa with Mercaptocarboxylate Inhibitor

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 PubMedThe VIM-2 metallo-beta-lactamase enzyme from Pseudomonas aeruginosa catalyzes the hydrolysis of most beta-lactam antibiotics including carbapenems, and there are currently no potent inhibitors of such enzymes. We found rac-2-omega-phenylpropyl-3-mercaptopropionic acid, phenylC3SH, to be a potent inhibitor of VIM-2. The structure of the VIM-2-phenylC3SH complex was determined by X-ray crystallography to 2.3 A. The structure revealed that the thiol group of phenylC3SH bridged to the two zinc(II) ions and the phenyl group interacted with Tyr67(47) on loop1 near the active site, by pi-pi stacking interactions. The methylene group interacted with Phe61(42) located at the bottom of loop1 through CH-pi interactions. Dynamic movements were observed in Arg228(185) and Asn233(190) on loop2, compared with the native structure (PDB code: 1KO3 ). These results suggest that the above-mentioned four residues play important roles in the binding and recognition of inhibitors or substrates and in stabilizing a loop in the VIM-2 enzyme.
