Two bacterial β1â4-galactosyltransferases, NmLgtB and Hp1â4GalT, exhibit promiscuous and complementary acceptor substrate specificity. They have been used in an efficient one-pot multienzyme system to synthesize LacNAc, lactose, and their derivatives including those containing negatively charged 6-O-sulfated GlcNAc and C2-substituted GlcNAc or Glc, from monosaccharide derivatives and inexpensive Glc-1-P.
两种细菌β1→4-半乳糖基转移酶,NmLgtB 和 Hp1→4GalT,表现出杂乱且互补的受体底物特异性。它们已被用于高效的一锅多酶系统中,以单糖衍生物和廉价的Glc-1-P为原料合成 LacNAc、乳糖及其衍生物,包括含有带负电的6-O-磺酸化GlcNAc和C2取代的GlcNAc或Glc的衍生物。
