2-heptyl-4(1H)-quinolone synthase.
based on mapping to UniProt Q9I4X1
Octanoyl-CoA + 2-aminobenzoylacetate = 2-heptyl-4(1H)-quinolone + CoA + CO(2) + H(2)O.
-!- The enzyme, characterized from the bacterium Pseudomonas aeruginosa, is a heterodimeric complex. -!- The PqsC subunit acquires an octanoyl group from octanoyl-CoA and attaches it to an internal cysteine residue. -!- Together with the PqsB subunit, the proteins catalyze the coupling of the octanoyl group with (2-aminobenzoyl)acetate, leading to decarboxylation and dehydration events that result in closure of the quinoline ring.
