TDP-3-dimethylamino-4,6-dideoxy-alpha-D-glucopyranose + 10-deoxymethynolide
dTDP + 10-deoxymethymycin
Substrates: dTDP-3-amino-4,6-dideoxy-alpha-D-glucopyranose i.e. dTDP-D-desosamine (a 14-membered macrolactone ring). The formation of aglycone is observed when 10-deoxymethymycin is incubated with an excess of TDP in the presence of DesVII-C-His6/DesVIII-N-Stag. The equilibrium of the reaction strongly favors the glycosylation direction because only less than 10% of 10-deoxymethylmycin is converted to 10-deoxymethynolide after a 24 h incubation period

Substrates: the enzyme can also recognize and process the linear precursor of its macrolactone substrate with reduced but measurable activity. The reaction is regioselective because only one singly glycosylated product is generated in each case despite the presence of multiple potential glycosylation sites. The substitution patterns nearby the glycosylation site, and not the ring conformation, are the major recognition determinants for glycosyltransferase

Substrates: the macrolide glycosyltransferase, DesVII/DesVIII, can recognize and process not only cyclic substrates of different ring size, but also a variety of linear substrates albeit with reduced, but measurable activities. When multiple hydroxyl groups are present, essentially no regiospecificity is observed for the linear substrates. Only singly glycosylated products are generated in all cases. In contrast, when cyclic substrates with multiple glycosylation sites are tested, the enzyme displays excellent regiospecificity in most cases
