Controlling the Selectivity and Stability of Proteins by New Strategies in Directed Evolution: The of addressing this crucial question. This chapter reviews the concept of ISM and its application in controlling the enantioselectivity and thermostability of enzymes, specifically those that have an organocatalytic mechanism. Illustrative examples include the directed evolution of lipases, Baeyer-Villigerases and epoxide hydrolases.
