Pichia pastoris GS115 were evaluated with a series of carbonyl compounds including aryl aldehydes, ketones, α- and β-ketoesters. This recombinant enzyme possessed a broad substrate profile with the ability of reducing both aldehydes and ketones. Especially, the enzyme catalyzed the double reduction of phenylglyoxal to (R)-1-phenyl-1,2-ethanediol with 99% yield and 99% ee by coupling with d-glucose dehydrogenase
用一系列包括芳基醛,酮,α-和β-酮酸酯的羰基化合物评估了毕赤酵母GS115的羰基还原酶的活性和对映选择性。该重组酶具有广泛的底物特征,具有还原醛和酮的能力。尤其是,该酶通过与d偶联,以99%的收率和99%ee催化苯乙二醛双还原为(R)-1-苯基-1,2-乙二醇。-葡萄糖脱氢酶用于辅因子NADPH的再生,代表通过仅使用一种酶有效还原一个分子中的醛和酮官能团的第一个例子。此外,这项研究为指导这种多功能生物催化剂的未来应用提供了有价值的信息。
