Cell density cultivation of recombinant Escherichia coli strains harboring the nodC gene (encoding chitooligosaccharide synthase) from Azorhizobium caulinodans has been previously described as a practical method for the preparation of gram-scale quantities of penta-N-acetyl-chitopentaose. We have now extended this method to the production of allylated derivative of penta-N-acetyl-chitopentaose by using allyl 2-acetamido-2-deoxy-beta-d-glucopyranoside (2) as the initial acceptor for the synthesis of target pentaoside in vivo.
先前已描述了携带来自茎瘤固氮根瘤菌的nodC基因(编码壳寡糖合酶)的重组大肠杆菌菌株的细胞密度培养,这是一种制备克级量的五-N-乙酰基壳五糖的实用方法。我们现在已将此方法扩展至通过使用烯丙基2-乙酰氨基-2-脱氧-β-D-吡喃葡萄糖苷(2)作为体内合成目标五糖的初始受体来生产五-N-乙酰基壳五糖的烯丙基化衍生物。
