摘要： A process for obtaining N-acetylneuraminic acid from N-acetylglucosamine is disclosed. The process is carried out in a reactor which contains both N-acylglucosamine-2-epimerase (E.C. 5.1.3.8) which isomerizes GlcNAc into ManNAc, and N-acetylneuraminic acid pyruvate lyase (E.C. 4.1.3.3) which catalyzes the reaction of the resulting ManNAc with pyruvic acid to give Neu5Ac. GlcNAc and Pyr are fed into the reactor and Neu5Ac is obtained in the outflow. The process is preferably carried out continuously and in particular in an enzyme membrane reactor at pH 7.5 and 25.degree. C., especially using residence times of 0.2 to 10 h, and with an excess of GlcNAc in comparison with Pyr which is subsequently added if necessary. Epimerase and lyase are preferably present in the reactor in a ratio of activities which is equivalent to the reciprocal value of the quotient of the conversion rates.
摘要翻译：公开了从N-乙酰葡糖胺获得N-乙酰神经氨酸的方法。该方法在含有将GlcNac异构化成ManNac的N-酰基葡糖胺-2-差向异构酶（EC 5.1.3.8）和N-乙酰神经氨酸丙酮酸裂合酶（EC 4.1.3.3）的反应器中进行，其催化所得到的 ManNac与丙酮酸反应得到Neu5Ac。将GlcNAc和Pyr进料到反应器中，并在流出物中获得Neu5Ac。该方法优选连续地，特别是在pH 7.5和25℃的酶膜反应器中进行，特别是使用0.2至10小时的停留时间，以及与Pyr相比过量的GlcNac，如果需要，随后加入。差向异构酶和裂解酶优选以相当于转化率的商的倒数值的活性比例存在于反应器中。
