The application of transition-state theory to enzymatic catalysis provides an approach to understanding enzymatic catalysis in terms of the factors that determine the strength of binding of ligands to proteins. The prediction that the transition state should bind to the enzyme much more tightly than the substrate is supported by the experimental results with stable analogs of transition states. Transition-state analogs have great potential for use in understanding enzymatic catalysis and in inhibiting enzymes. Because of their potency and specificity as enzyme inhibitors, some of them may become very useful chemotherapeutic agents.
