2.4.1.302 | dTDP-beta-L-noviose + novobiocic acid |
sequential bi-bi catalytic mechanism. NovM binds to both donor and acceptor substrate (novobiocic acid and dTDP-L-noviose) to form a ternary complex, during which process the noviose sugar is transferred from dTDP-L-noviose to novobiocic acid. The glycosylated product, demethyldecarbamoyl novobiocin, is subsequently released from the complex |
