Catalyzes the transfer of L-noviose from dTDP-4-O-demethyl-beta-L-noviose to the phenolic oxygen of novobiocic acid, creating the full ABC ring system in the novobiocin biosynthesis pathway. Novobiocin is an aminocoumarin family antibiotic that targets bacterial DNA gyrases. Also shows activity with variant coumarin aglycones, suggesting it may be a promiscuous catalyst for noviosylation of a range of planar scaffolds. Does not show activity with TDP-L-rhamnose. dTDP-4-O-demethyl-beta-L-noviose + novobiocic acid = desmethyldescarbamoylnovobiocin + dTDP + H(+) Inhibited by TDP-L-rhamnose, the sugar donor that most closely structurally resembles the natural substrate dTDP-beta-L-noviose. kcat is 313 min(-1) with novobiocic acid as substrate. Antibiotic biosynthesis; novobiocin biosynthesis. Belongs to the glycosyltransferase 28 family.
