  On the substrate preference of glutaryl acylases

  摘要：

  The substrate preferences of three acylases two wild-type enzymes and an evolved variant obtained by directed evolution - which are prototypical enzymes for glutaryl-7-ACA acylase and cephalosporin C acylase subfamilies, have been investigated. A preliminary screening of enzymes' performances on a large set of substrates has been carried out by a colorimetric assay performed in 96-well plates and by a pH-Star monitoring the hydrolytic activities. Subsequently, kinetic data for selected substrates have been determined, thus elucidating the substrate preference of members of glutaryl-7-ACA acylase vs. cephalosporin C acylase subfamilies. These achievements pave the way to the ability of choosing the best enzyme for the hydrolysis of different compounds of industrial importance. (C) 2011 Elsevier B.V. All rights reserved.

• Kinetic resolutions of racemic amines and alcohols catalyzed by an industrial glutaryl-7-aminocephalosporanic acid acylase with unexpected broad substrate specificity

  日期：2003.5

  An industrial glutaryl-7-aminocephalosporanic acid acylase (GAR) possesses a significant broad substrate specificity that crosses over the usual cephalosporanic skeleton. Enantioselective amidase and even esterase activities have been observed with all the glutarates of racemic substrates investigated, with a stereopreference for the (S)-enantiomer. The different physical-chemical properties of reagents and products allow their easy separation by solvent extraction, avoiding cumbersome chromatography or distillation processes during reaction work-up.
