General Information

General Information Comment Organism
physiological function 4-hydroxy-2-alkylquinoline biosynthesis, which requires the PqsABCD enzymes, proceeds by a two-step pathway: PqsD mediates the synthesis of 2-aminobenzoylacetate from anthraniloyl-coenzyme A and malonyl-coenzyme A, then the decarboxylating coupling of 2-aminobenzoylacetate to an octanoate group linked to PqsC produces 4-hydroxy-2-heptylquinoline, the direct precursor of 3,4-dihydroxy-2-heptylquinoline. PqsB is tightly associated with PqsC and required for the second step. None of the pqsA-, pqsB-, pqsC-, and pqs- mutants produces measurable amounts of 4-hydroxy-2-alkylquinolines, and PqsB and PqsC have to be present simultaneously to transform the intermediate into 4-hydroxy-2-heptylquinoline Pseudomonas aeruginosa
