FTMS monitoring of the loading of benzoate and salicylate on the ACP EncC. A. ATP (10 mM)-dependent transfer of benzoic acid (10 mM) by EncN (2 µM) on holo-EncC (20 µM); B. Sfp-catalyzed phosphopanthetheinylation of apo-EncC (20 µM) by benzoyl-CoA7 (~0.25 mM) generated in situ; C. Same reaction conditions as panel A except that equimolar amounts of benzoic, salicylic, and 2,3-dihydroxybenzoic acids were added; and D. Same reaction conditions as panel A except that benzoic acid was omitted.
