A High‐Throughput Screening Method for Chiral Alcohols and its Application to Determine Enantioselectivity of Lipases and Esterases
ChemcatchemPeer ReviewedBustosJaimes Ismael +62009Journals
A new colorimetric method to determine the enantiopurity of chiral alcohols is presented based on enantioselective oxidation by two alcohol dehydrogenases. The oxidation of either ( R )‐ or ( S )‐alcohol produces NADPH (or NADH), which reduces 2‐(4‐iodophenyl)‐3‐(4‐ nitrophenyl)‐5‐phenyl‐2 H ‐tetrazolium to its corresponding formazan derivative. Application of this method to screen lipase variant libraries for enantioselective hydrolysis is also described.
