ID 1.14.13.182 DE 2-heptyl-3-hydroxy-4(1H)-quinolone synthase. AN 2-heptyl-3,4-dihydroxyquinoline synthase. CA 2-heptyl-4(1H)-quinolone + H(+) + NADH + O2 = 2-heptyl-3-hydroxy-4(1H)- CA quinolone + H2O + NAD(+). CC -!- The enzyme from the bacterium Pseudomonas aeruginosa catalyzes the CC terminal step in biosynthesis of the signal molecule 2-heptyl-3,4- CC dihydroxyquinoline that plays a role in regulation of virulence CC genes.
