Escherichia coli K-12 substr. MG1655 Enzyme: enterochelin esterase



Gene: fes Accession Numbers: EG10299 (EcoCyc), b0585, ECK0577

Regulation Summary Diagram: ?

Summary:
Enterochelin (enterobactin) esterase (Fes) catalyzes the hydrolysis of both enterobactin and ferric enterobactin. The enzyme produces the linear 2,3-dihydroxy-N-benzoyl-L-serine trimer as well as the dimer and monomer [OBrien71, Langman72, Greenwood78, Winkelmann94]. Hydrolysis of ferric enterobactin is less efficient than hydrolysis of unliganded enterobactin [Brickman92].

Expression of fes is increased by iron limitation [Pettis87, Pettis88]; repression under iron-replete conditions is mediated by Fur [Hunt94, Escolar98]. fes is more highly expressed at 37°C than at 23°C during growth in minimal media; expression under iron-depleted conditions is high at both growth temperatures [WhiteZiegler07].

When grown under conditions of iron limitation, fes mutants require the presence of added citrate [Langman72]. A fes mutant is more sensitive to near-UV radiation than wild type [Hoerter96] and is highly sensitive to the ferrous iron chelator 2,2'-dipyridyl [Wang11i]. A fes insertion mutant shows a SpoT-dependent increase in the ppGpp pool [Vinella05].
