ENZYME entry: EC 2.3.1.262

Accepted Name
anthraniloyl-CoA anthraniloyltransferase.
Reaction catalysed
anthraniloyl-CoA + H(+) + malonyl-CoA <=> (2-aminobenzoyl)acetyl-CoA + CO2 + CoA
Comment(s)
  • 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.
