Protein
8-demethylnovobiocic acid synthase
Organism
Streptomyces niveus
Function
Catalyzes the formation of an amide bond between 3-dimethylallyl-4-hydroxybenzoate (ring A of novobiocin) and 3-amino-4,7-dihydroxycoumarin (ring B of novobiocin) in an ATP-dependent reaction in the novobiocin biosynthesis pathway. Novobiocin is an aminocoumarin family antibiotic that targets bacterial DNA gyrases.
Similarity
Belongs to the ATP-dependent AMP-binding enzyme family.
