Figure 5

Model of 16G3 with bound hapten showing the three sculpted binding pockets (Left) and key residues (Right). His L34 serves as a H-bond donor for the P Created by potrace 1.16, written by Peter Selinger 2001-2019 O of the hapten and for the oxygen anion of the transition state. Gly H95 and Gly H35 allow easy access for the p-nitrophenyl ester group of the electrophile to its binding pocket. Pro H100B and a Tyr (not shown) sandwich the cyclohexyl group of the hapten. The binding site for the Trp of the nucleophile is not well defined but includes Tyr H97.
