Effects of crown ethers and small amounts of cosolvent on the activity and enantioselectivity of a-chymotrypsin in organic solvents
Addition of crown ethers to a-chymotrypsin, subtilisin, and other proteases considerably enhances the activity of these enzymes in transesterification reactions Of N-acetyl-alanine and -phenylalanine esters in organic solvents. Even much higher enhancements of activity (up to 640 x) are obtained by prior lyophilization of the enzymes in the presence of 18-crown-6. Several possibilities for the ...
