Figure 1. Chemical transformation resulting from antibody-catalyzed prodrug activation and chemical formulae of the compounds used in this study. Antibodies 6D9 and 9C10 were raised against chloramphenicol phosphonate 3 and catalyze the hydrolysis of chloramphenicol ester 1 to generate chloramphenicol 2 and the acid product. Sub-Lys (4) was used for the ITC study.
