Novel enzymes that stereoselectively reduce imine derivatives were isolated and purified, and polynucleotides encoding the enzymes were cloned. Optically active amine derivatives were produced by acting on imine derivatives with a culture of microorganisms having the ability to stereoselectively reduce the compounds, microbial cells or processed products thereof, and/or imine reductases thereof, followed by collecting the generated optically active amine derivatives. The present invention enables, for example, production of an optically active compound represented by formula (IV):
(wherein R group represents an alkyl group having one to three carbon atoms; and n represents an integer of 1 to 4).
本发明分离和纯化了立体选择性还原亚胺衍生物的新型酶,并克隆了编码该酶的多核苷酸。通过使用具有立体选择性还原化合物能力的微生物培养物,微生物细胞或其处理产品和/或亚胺还原酶,对亚胺衍生物进行作用,生成光学活性胺衍生物,然后收集所产生的光学活性胺衍生物。例如,本发明使得能够生产由公式(IV)表示的光学活性化合物:(其中R基表示具有1至3个碳原子的烷基;n表示1至4的整数)。
