title: Differences in protein structure and similarities in catalytic function of two L-stereoselective carbonyl reductases from bakers' yeast.
abstract: We purified and studied two L-stereoselective carbonyl reductases from bakers' yeast (Saccharomyces cerevisiae). One catalyzed exclusively the enantioselective reduction of carbonyl compounds such as beta-keto esters and the other acted on alpha-acetoxy ketones and beta-keto esters. The enzymes had identical molecular weights and catalyzed the L-stereoselective reduction of various carbonyl compounds with similar substrate specificity, but they were different proteins coded by different genes.
