The research investigates how substrate solvation affects the enantioselectivity of subtilisin, an enzyme, toward secondary alcohols. The purpose is to resolve inconsistencies in predicting enantiopreference of subtilisin in different solvents and to provide a more accurate model for designing enantioselective reactions. The study proposes a revised rule that subtilisin binds only one substituent of a secondary alcohol in its S1′ pocket, leaving the other in the solvent. This rule explains why solvent changes alter enantioselectivity and suggests that solvation of one substituent contributes to enantiopreference. Key chemicals include secondary alcohols like 1a-13a, dihydrocinnamoyl esters, and arylsulfinamides, which were used to test the revised rule. The study concludes that enantioselectivity in water varies linearly with the hydrophobicity difference between substituents, and increasing the polarity difference between substituents can enhance enantioselectivity. This model provides a strategy to improve enantioselectivity by modifying substrates and offers insights into how solvents influence enzyme-catalyzed reactions.
