Accepted name: 2-heptyl-3-hydroxy-4(1H)-quinolone synthase
Reaction: 2-heptyl-4(1H)-quinolone + NADH + H+ + O2 = 2-heptyl-3-hydroxy-4(1H)-quinolone + NAD+ + H2O
Glossary: 2-heptyl-4(1H)-quinolone = 2-heptyl-4-hydroxyquinoline
2-heptyl-3-hydroxy-4(1H)-quinolone = 2-heptyl-3,4-dihydroxyquinoline
Other name(s): PqsH; 2-heptyl-3,4-dihydroxyquinoline synthase
Systematic name: 2-heptyl-4(1H)-quinolone,NADH:oxygen oxidoreductase (3-hydroxylating)
Comments: The enzyme from the bacterium Pseudomonas aeruginosa catalyses the terminal step in biosynthesis of the signal molecule 2-heptyl-3,4-dihydroxyquinoline that plays a role in regulation of virulence genes.
