advantage of relaxed donor specificity and strict acceptor specificity of glycosyltransferases to label target glycan epitopes with bioorthogonal reactivegroups carried by unnatural nucleotide sugars in vitro. The subsequent covalent conjugation by bioorthogonal chemical reactions with either fluorescent or affinity tags allows further visualization, quantification, or enrichment of target glycan epitopes

The actinopyrone biosyntheticgenecluster (atpn) lacks glycosyl- and methyltransferase genes, yet its product clearly calls for such enzymes. Using bioinformatics and biochemical methods, we confirmed that the mt3913 and gt723 genes, well beyond the atpn cluster boundaries, encode methyltransferase and glycosyltransferase, respectively. Moreover, homologous protein GT1507 enabled us to produce 14
