Enzyme Information

Anthraniloyl-CoA anthraniloyltransferase.
based on mapping to UniProt P20582
Anthraniloyl-CoA + malonyl-CoA = 2-aminobenzoylacetyl-CoA + CoA + CO(2).
-!- The enzyme, characterized from the bacterium Pseudomonas aeruginosa, participates in the synthesis of the secondary metabolites 2-heptyl- 3-hydroxy-4(1H)-quinolone and 4-hydroxy-2(1H)-quinolone. -!- The enzyme transfers an anthraniloyl group from anthraniloyl-CoA to an internal L-cysteine residue, followed by its transfer to malonyl- CoA to produce a short-lived product that can cyclize spontaneously to form 4-hydroxy-2(1H)-quinolone. -!- However, when EC 3.1.2.32 is present, it removes the CoA moiety from the product, forming the stable 2-aminobenzoylacetate.
