6.3.1.15 | ATP + 3-dimethylallyl-4-hydroxybenzoate + 3-amino-4,7-dihydroxy-8-methylcoumarin |
in the sequential bi-bi catalytic mechanism, NovL binds to the benzoic acid moiety and the aminocoumarin ring to form a ternary complex, catalyzes the ligation between substrates inside the complex, and subsequently releases the reaction products, novobiocic acid and water |

6.3.1.15 | ATP + 3-dimethylallyl-4-hydroxybenzoate + 3-amino-4,7-dihydroxy-8-methylcoumarin |
the formation of an acyl adenylate from ring A and ATP is demonstrated by an ATP-PPi exchange assay. The purified nzyme exhibits both activation and transferase activity, i.e. it catalyzed both the activation of ring A as acyl adenylate and the subsequent transfer of the acyl group to the amino group of ring B. The reaction is specific for ATP as nucleotide triphosphate |
