Accepted name: |
L-demethylnoviosyl transferase |
Reaction: |
dTDP-4-O-demethyl-β-L-noviose + novobiocic acid = dTDP + demethyldecarbamoyl novobiocin
|
Glossary: |
novobiocic acid = N-(2,7-dihydroxy-8-methyl-4-oxo-4H-chromen-3-yl)-4-hydroxy-3-(3-methylbut-2-en-1-yl)benzamide
dTDP-4-O-demethyl-β-L-noviose = dTDP-6-deoxy-5-methyl-β-L-altropyranose = dTDP-(2S,3R,4R,5R)-6,6-dimethyltetrahydro-2H-pyran-2,3,4,5-tetraol
demethyldecarbamoyl novobiocin = N-{7-[(6-deoxy-5-methyl-β-D-gulopyranosyl)oxy]-4-hydroxy-8-methyl-2-oxo-2H-chromen-3-yl}-4-hydroxy-3-(3-methylbut-2-en-1-yl)benzamide |
Other name(s): |
novM (gene name); dTDP-β-L-noviose:novobiocic acid 7-O-noviosyltransferase; L-noviosyl transferase |
Systematic name: |
dTDP-4-O-demethyl-β-L-noviose:novobiocic acid 7-O-[4-O-demethyl-L-noviosyl]transferase |
Comments: |
The enzyme is involved in the biosynthesis of the aminocoumarin antibiotic, novobiocin. |
