Fig. 1. Chemical reaction catalyzed by D2.3 and structures of the compounds used in this study. Ester 1 is a substrate hydrolyzed^ by D2.3. Crystal structures examined are those of complexes of^ D2.3 with p-nitrobenzyl alcohol 2 (one of the products of the hydrolysis of 1), p-nitrobenzyl phosphonate 3^ (the TSA hapten used to elicit D2.3), and p-nitrobenzyl amide^ 4, a stable analogue of the substrate ester 1.
