Figure 3From: Enzymatic analysis of the effect of naturally occurring Leu138Pro mutation identified in SHV β-lactamase on hydrolysis of penicillin and ampicillinModeled docking structures of β-lactamases and penicillin and ampicillin. (A) Docking structure of the wild-type and penicillin (B) Docking structure of wild-type and ampicillin (C) Docking structure of L138P mutant and penicillin (D) Docking structure of L138P mutant and ampicillin. The dashed lines indicate hydrogen bonds and the red residues indicate catalytic residues.Back to article page
