Abstract
AbstractAntibodies have now been shown to catalyze a variety of chemical transformations, including hydrolytic, concerted, and bimolecular reactions. The inherent chirality of the antibody binding pocket has been exploited to exert precise stereochemical control over their catalyzed reactions. The mechanisms by which antibodies catalyze reactions are not expected to differ in any general way from those of natural enzymes. Antibodies use their binding energy to stabilize species of higher free energy which appear along the reaction coordinate or effect general acid/base catalysis. The advent of catalytic antibodies promises new catalysts that extend the range of catalysis by proteins to chemical transformations that were not required during the evolution of enzymes.
