Explain how chymotrypsin combine different modes of catalysis( acid/base and covalent chemistry; proximity effects and transition state binding/stabalization) to acheive the rate enhancement observed for enzyme catalyzed reactions.
Give examples of specific events, structures, and active site features that contribute to the chemistry and bindin/orientation effects important for the catalytic mechanism responsible for conversion of substrate to product.
