Enzymatic N‐Glycosylation of Diverse Arylamine Aglycones by a Promiscuous Glycosyltransferase from Carthamus tinctorius
2017
A new glycosyltransferase (UGT71E5) from Carthamus tinctorius exhibited a robust promiscuity towards 30 structurally diverse drug-like aromatic amine scaffolds, making it the first reported glycosyltransferase capable of catalyzing N-glycosylation with multiple diverse nitrogen-heterocyclic aromatic compounds. The catalytic promiscuity and reversibility of UGT71E5 was exploited to generate the rare N-glycoside from the abundant O-glycoside with high efficiency. These findings demonstrate the significant potential of UGT71E5 in the enzymatic synthesis of diverse bioactive N-glycosides.
