ID 2.3.1.262 DE anthraniloyl-CoA anthraniloyltransferase. CA anthraniloyl-CoA + H(+) + malonyl-CoA = (2-aminobenzoyl)acetyl-CoA + CA CO2 + CoA. CC -!- The enzyme, characterized from the bacterium Pseudomonas aeruginosa, CC participates in the synthesis of the secondary metabolites 2-heptyl- CC 3-hydroxy-4(1H)-quinolone and 4-hydroxy-2(1H)-quinolone. CC -!- The enzyme transfers an anthraniloyl group from anthraniloyl-CoA to CC an internal L-cysteine residue, followed by its transfer to malonyl- CC CoA to produce a short-lived product that can cyclize spontaneously CC to form 4-hydroxy-2(1H)-quinolone. CC -!- However, when EC 3.1.2.32 is present, it removes the CoA moiety from CC the product, forming the stable 2-aminobenzoylacetate. DR P20582, PQSD_PSEAE ; //
