description: This entry represents the N-terminal domain of enterochelin esterase. The activity of the
  enzyme has been characterised [[cite:PUB00053482],[cite:PUB00097189]]. Fes catalyses the hydrolysis
  of the 2,3-dihydroxy-N- benzoyl-L-serine trimer, enterochelin, forming 2,3- dihydroxybenzoylserine.
  It also catalyses hydrolysis of free enterobactin and ferric enterobactin. Upon hydrolysis of ferric
  enterobactin by Fes, released iron is probably reduced by a second enzyme. Enterochelin esterase represents
  a family of non-peptidase homologues belonging to the MEROPS peptidase family S9, clan SC.
