EC is Orphan !
Common name :Enterobactin synthase

Systematic name :2,3-dihydroxybenzoate:L-serine ligase

Other names :2,3-dihydroxybenzoylserine synthetase
N-(2,3-dihydroxybenzoyl)-serine synthetase
2,3-dihydroxybenzoate--serine ligase
Comments :This enzyme complex catalyzes the conversion of three molecules each of 2,3-dihydroxybenzoate and L-serine to form the siderophore enterobactin. In Escherichia coli the complex is formed by EntB (an aryl carrier protein that has to be activated by 4'-phosphopantetheine), EntD (a phosphopantetheinyl transferase that activates EntB), EntE (catalyzes the ATP-dependent condensation of 2,3-dihydroxybenzoate and holo-EntB to form the covalently arylated form of EntB), and EntF (a four domain protein that catalyzes the activation of L-serine by ATP, the condensation of the activated L-serine with the activated 2,3-dihydroxybenzoate, and the trimerization of three such moieties to a single enterobactin molecule).
