A process for enzymatic oxidation of a terminal group of a linear carbohydrate is disclosed, wherein a carbohydrate of formula (I): TU-X-Y-TOG, wherein TU is a terminal unit selected from -CH2OH, -CHO, -COOH, and -C1-C4 alkyl; X is a linear carbohydrate chain comprising 0 to 18 units [CR1R2], wherein in each unit R1 and R2 independently can be hydrogen, hydroxyl, C1-C4 alkyl, or can together form a keto group, Y is -CHOH, -CHNH2 or -CHSH and TOG is an oxidzable terminal unit selected from -CH2OH and -CHO; is contacted with an NAD+ dependent short chain dehydrogenase/reductase for oxidation of TOG.
本发明公开了一种线性碳水化合物末端基团的酶促氧化工艺,其中碳水化合物为式(I):TU-X-Y-TOG,其中 TU 是选自-CH2OH、-CHO、-COOH 和-C1-C4 烷基的末端单元;X 是由 0 至 18 个单元组成的线性碳水化合物链[CR1R2],其中每个单元中的 R1 和 R2 可独立地为氢、羟基、C1-C4 烷基或可共同形成酮基,Y 是-CHOH、-CHNH2 或-CHSH,TOG 是选自-CH2OH 和-CHO 的可氧化末端单元;与依赖于 NAD+ 的短链脱氢酶/还原酶接触以氧化 TOG。
