LITERATURE
S24P/G182A/G196A/H222D/S250E/S254R
-
the mutant CbADH-6M exhibits a favorable soluble and highly active expression with an activity of 46.3 U/ml, which is 16times higher than the wild-type (2.9 U/ml) and a more stable protein conformation with an enhanced thermal stability. The activity of CbADH-6M is upgraded to 2401.8 U/ml by high cell density fermentation strategy using recombinant Escherichia coli. Improving CbADH solubility by chaperone buffering. The efficiency for NADPH regeneration of the mutant enzyme is testified in the synthesis of some fine chiral aromatic alcohols coupling with another ADH from Lactobacillus kefir (LkADH). Method optimization, overview. Although the Asp225-His222 salt bridge in the original wild-type CbADH protein disappears due to the amino acid substitution H222D, the replacement of H222D, S250E and S254R leads to the formation of four new salt bridges including Arg254-Glu250, Arg254-Asp225, Arg254-Glu280 and Arg254-Asp222, which constitute a salt bridge network centered on Arg254
