-
the mutant exhibits higher activity but decreased affinity toward aliphatic alcohols, aldehydes as well as NAD+ and NADH compared to the wild type enzyme, optimum pH is at about pH 8.6
I86A
site-directed mutagensis, the secondary alcohol dehydrogenase I86A mutant is stereospecific for (R)-alcohols instead of (S)-alcohols, in contrast to the wild-type enzyme, the mutation I86A allows large substituents to fit into the large pocket of I86ATeSADH, which corresponds to the small pocket in wild-type TeSADH, modeling of the stereopreference of TeSADH I86A
