Glossary: decarbamoylnovobiocin = N-{7-[(6-deoxy-5-methyl-4-O-methyl-β-D-gulopyranosyl)oxy]4-hydroxy-8-methyl-2-oxo-2H-chromen-3-yl}-4-hydroxy-3-(3-methyl-2-buten-1-yl)benzamide

Other name(s): novN (gene name)

Systematic name: carbamoyl phosphate:decarbamoylnovobiocin 3''-O-carbamoyltransferase

Comments: The enzyme catalyses the last step in the biosynthesis of the aminocoumarin antibiotic novobiocin. The reaction is activated by ATP [1].
