Prelog and anti-Prelog stereoselectivity of two ketoreductases from Candida glabrata.

Two ketoreductases from Candida glabrata were used for the asymmetric reduction of prochiral substituted acetophenones displayed different enantiopreference toward para-, meta-substituted and ortho-halogen substituted acetophenones with excellent enantioselectivity. Homology modeling and docking analysis were in conformity with this interested enantiopreference obtained from experimental tests. The reduction of a series of other substituted aryl ketones was also investigated using the two ketoreductases.
