Substrate flexibility of a 2,6-dideoxyglycosyltransferase

Abstract
We report the first 2,6-dideoxysugar-O-glycosyltransferase with substrate flexibility at the 2 position, confirm the function of a putative NDP-hexose 2,3-dehydratase in the jadomycin B biosynthetic gene cluster and deduce the substrate flexibility of downstream enzymes in L-digitoxose assembly, enabling reprogramming of biosynthetic gene clusters to modify sugar substituents.
