   2.3.1.262 | metabolism |
PqsD is an enzyme essential for the Pseudomonas aeruginosa quorum-sensing apparatus, which catalyzes the final and key step in the biosynthesis of 4-hydroxy-2-heptylquinolone, which is a signal molecule of the Pseudomonas aeruginosa quorum-sensing system |

| 2.3.1.262 | physiological function |
4-hydroxy-2-alkylquinolines biosynthesis requires the PqsABCD enzymes and proceeds by a two-step pathway: First, PqsD mediates the synthesis of 2-aminobenzoylacetate from anthraniloyl-CoA and malonyl-CoA, then the decarboxylating coupling of 2-aminobenzoylacetate to an octanoate group linked to PqsC produces 4-hydroxy-2-heptylquinoline, the direct precursor of Pseudomonas quinolone signal. PqsB is tightly associated with PqsC and required for the second step |

| 2.3.1.262 | physiological function |
in addition to PqsABCD, PqsE has a role in 2-heptyl-4(1H)-quinolone synthesis. PqsE acts as thioesterase, hydrolyzing the biosynthetic intermediate 2-aminobenzoylacetyl-coenzyme A formed by PsqD to form 2-aminobenzoylacetate, the precursor of 2-heptyl-4(1H)-quinolone and 2-aminoacetophenone |
