Animal sera were screened for an alternative enzyme source of α1,3-fucosyltransferase, and the highest activity was observed in chicken serum. A partially purified enzyme fraction almost devoid of coexisting glycosidases was prepared from the chicken serum, and used for the fucosylation of LacNAc compounds. The enzyme reaction was efficient enough to allow the one-pot preparation of designed Lex compounds such as LNFP III.
对动物血清进行了筛选,以寻找α1,
3-岩藻糖基转移酶的替代酶源,结果发现鸡血清中的岩藻糖基转移酶活性最高。从鸡血清中制备了部分纯化的酶组分,几乎不含共存的糖苷酶,用于 LacNAc 化合物的岩藻糖基化。这种酶反应的效率很高,足以一次过制备出设计的Lex化合物,如LNFP III。
