The present invention relates to the preparation of amines from aldehydes and ketones by reductive amination with enzymes having a reductive aminase activity on aldehydes and ketones devoid of any carboxyl group gamma of the carbonyl group. The invention also relates to the enzymes per se and their uses in biocatalysis. The enzymes are derived from Mycobacterium smegmatis and vaccae, Cystobacter fuscus, Microbacterium sp. and Aminomonas paucivorans.
本发明涉及用对醛和酮具有还原胺酶活性的酶,通过对羰基上没有任何羧基γ的醛和酮进行还原胺化,从醛和酮制备胺。本发明还涉及酶本身及其在
生物催化中的用途。这些酶来源于烟曲霉(Mycobacterium smegmatis)和芽孢杆菌(Cystobacter fuscus)、微杆菌(Microbacterium sp.)和
氨单胞菌(Aminomonas paucivorans)。
