    6.2.1.32 | ATP + anthranilate + CoA = AMP + diphosphate + anthraniloyl-CoA |
reaction via anthraniloyl-AMP intermediate. The catalytic cycle of PqsA consists of two steps: in the first half-reaction of PqsA (adenylation), anthranilate is activated with ATP/Mg2+ to produce the intermediate anthraniloyl-AMP with the release of diphosphate. The aryl moiety is then transferred to the acceptor molecule CoA to form anthraniloyl-CoA in the second half-reaction (thioester formation). The two half-reactions are cooperatively catalyzed by a large N-terminal domain and a smaller C-terminal domain separated by a flexible linker, the latter undergoes large conformational rearrangements in the course of the catalytic cycle |
