Galacto-N-biose (GNB) derivatives were efficiently synthesized from galactose derivatives via a one-pot two-enzyme system containing two promiscuous enzymes from Bifidobacterium infantis: a galactokinase (BiGalK) and a d-galactosyl-β1-3-N-acetyl-d-hexosamine phosphorylase (BiGalHexNAcP). Mono-sialyl and di-sialyl galacto-N-biose derivatives were then prepared using a one-pot two-enzyme system containing a CMP-sialic acid synthetase and an α2-3-sialyltransferase or an α2-6-sialyltransferase.
通过包含来自婴儿双歧杆菌的两种混杂酶的一锅双酶系统,由半乳糖衍生物高效合成了半乳糖-N-双糖(GNB)衍生物:一种半乳糖激酶(BiGalK)和一种D-半乳糖基-β1-3-N-乙酰-D-己糖胺磷酸化酶(BiGalHexNAcP)。然后使用包含CMP-唾液酸合成酶和α2-3-唾液酸转移酶或α2-6-唾液酸转移酶的一锅双酶系统制备了单唾液酸和双唾液酸半乳糖-N-双糖衍生物。
