== Function ==
[https://www.uniprot.org/uniprot/ENTB_ECOLI ENTB_ECOLI] Required for production of 2,3-DHB. Also serves as an aryl carrier protein and plays a role in enterobactin assembly.[https://www.uniprot.org/uniprot/ENTE_ECOLI ENTE_ECOLI] Activates the carboxylate group of 2,3-dihydroxy-benzoate (2,3-DHB), via ATP-dependent PPi exchange reactions, to the acyladenylate. Then, catalyzes the acylation of holo-EntB with 2,3-DHB adenylate, preparing that molecule for amide bond formation with L-serine.
