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.
我们从面包酵母（酿酒酵母）中纯化并研究了两种L-立体选择性羰基还原酶。一种专门催化羰基化合物如β-酮酯的对映选择性还原，另一种作用于α-乙酰氧基酮和β-酮酯。这两种酶具有相同的分子量，并且以相似的底物特异性催化各种羰基化合物的L-立体选择性还原，但它们是由不同基因编码的不同蛋白质。
