Preparation of diverse glycans is essential to glycobiology, while syntheticallyusefulenzymes for this purpose are limited. This study discovered a general tolerance of galactosyltransferases (GalTs) toward uncommon donor UDP-galactosamine. A two-step strategy was devised to harness this property for the facile synthesis of GalNAc-glycosides.
