Use of novel mutant galactosyltransferase for the bioconjugation of terminal N-Acetylglucosamine (GlcNAc) residues on live cell surface

Based on the crystal structure of bovine β4Gal-T1 enzyme, mutation of a single amino acid Y289 to L289 (Y289L) changed its donor specificity from Gal to N-acetyl-galactosamine (GalNAc). A chemoenzymatic method that uses GalNAc analogues like GalNAz or 2-keto-Gal as sugar donors with the enzyme Y289L...
