  Rapid screening of hydrolases for the enantioselective conversion of ‘difficult-to-resolve’ substrates

  摘要：

  Hydrolases showing high enantio selectivity towards three racemic alcohols ( 1-methoxy-2-propanol, 3-hydroxy-tetrahydrofuran, 3-butyn-2-ol) and pantolactone were identified by a step-wise screening procedure. Initially, those biocatalysts, which exhibited hydrolytic activity towards the corresponding acetates or butyrates, were selected out of >100 enzymes. Here, rapid screening was performed in a pH-indicator-based format in microtiter plates. Subsequently, enantioselectivity of active hydrolases was determined in small scale reactions (similar to1 mg substrate per reaction) by means of gas chromatography using chiral columns. Enzymes exhibiting highest enantioselectivities were then chosen for preparative scale resolution. Using this strategy, at least one suitable hydrolase was found for 3 out of the 4 model compounds examined, allowing efficient kinetic resolution. Moreover, in all cases enantiocomplementary enzymes were identified thus enabling access to both enantiomers of all substrates. (C) 2001 Elsevier Science Ltd. All rights reserved.

  Glycol ether acetates, and in particular propylene glycol alkyl (or aryl) ether acetates, can be resolved enzymatically by enantioselective hydrolysis with a hydrolase at high concentrations of substrates; in some embodiments, the hydrolase is a lipase. Glycol ethers, and in particular propylene glycol alkyl (or aryl) ethers, can be resolved enzymatically by enantioselective transesterification with a hydrolase, in the presence of an acyl donor, at high concentrations of substrates; in some embodiments, the hydrolase is a lipase.
