Enzymatic rate enhancements arise from the unmatched ability of enzymes to stabilize the transition states of the reactions that they catalyse. The purpose of this article is to discuss the magnitude and mechanistic origins of enzymatic rate enhancements. Selected enzymes are described that manifest a wide range of rate enhancements and corresponding catalytic strategies.
