1.1.1.B3 | 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 |

1.1.1.B3 | W110A/I86A |
the mutant enzyme is completely non-stereoselective for the reduction of 2-hexanone.Additionally, an extremely low level of stereoselectivity (i.e. from 10% to 24%) is observed for the reduction of aryl-aliphatic ketones and aliphatic ketones |
