Molecular Basis and Engineering of Enzymes Stereospecificity

Molecular recognition, particularly enantiomeric specificity of biological molecules is a key consideration in designing drugs, pharmaceutical intermediate and in industrial production of chirally active intermediate. Although the molecular bases of many enzymes stereospecificity are not completely delineated, a number of protein engineering studies were able to enhance and even in some cases invert the stereospecificity of various enzymes. Herein, we review the current understanding on enzymes stereospecificity, and the effects of mutations to the stereospecific pockets due to enzymes engineering to improve stereospecificity.
