    Abstract:
    The high binding affinity and specificity of antibodies for a great variety of ligands has been widely exploited in structure-activity relationship studies of biomolecules and more recently in the development of new catalysts for several chemical reactions. It is assumed that antibodies generated against haptenic protease inhibitors would recognize both these haptens and the substrate of the model proteolytic reaction. We have produced antibodies against HIV PRp12 aspartyl protease substrate analogues, chemically modified at the scissile bond, Phe-Pro. Identical chemical modifications have been reported for related HIV protease inhibitors. We finally selected an anti-hapten monoclonal antibody that specifically recognized the substrate and those haptens with both the phenylalanyl side chain and the prolyl pyrrolidine ring. This selectivity of recognition suggests that such an antibody might mimic the catalytic site of the model protease.
