Wild-type Candida tenuisxylose reductase and two Trp-23 mutants thereof catalyze NADH-dependent reduction of a homologous series of aromatic α-keto esters with absolute pseudo re-face stereoselectivity and broad tolerance for the substituent on the aromatic ring, producing the corresponding R-alcohols in high yield.
野生型白色念珠菌十糖还原酶及其两个 Trp-23 突变体能催化 NADH 依赖性还原一系列同源的芳香族δ-酮酯,具有绝对的假重面立体选择性和对芳香环上取代基的广泛耐受性,并能以高产率生成相应的 R-醇。
