A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 6.3.2.14

Accepted Name
Enterobactin synthase.
Alternative Name(s)
2,3-dihydroxybenzoate--serine ligase.
N-(2,3-dihydroxybenzoyl)-serine synthetase.
Reaction catalysed
6 ATP + 3 2,3-dihydroxybenzoate + 3 L-serine <=> enterobactin + 6 AMP + 6 diphosphate
Comment(s)
  • 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).
