Stereospecificity of the ferric enterobactin receptor of Escherichia coli K-12.

چکیده
Synthetic enterobactin and enantioenterobactin (D-seryl enterobactin) have been examined for the ability to transport iron in Escherichia coli. Failure of the unnatural, D-serine-derived material to support growth of E. coli mutants indicates outer membrane receptor specificity for the naturally occurring complex having an L-seryl backbone and the delta-cis configuration of the Fe(III).catecholate center. Enantioenterobactin was markedly less effective in protecting cells against colicin B compared to synthetic or natural enterobactin.

Recognition and transport of ferric enterobactin in Escherichia coli.
The specificity of the outer membrane protein receptor for ferric enterobactin transport in Escherichia coli and the mechanism of enterobactin-mediated transport of ferric ions across the outer membrane have been studied. Transport kinetic and inhibition studies with ferric enterobactin and synthetic structural analogs have mapped the parts of the molecule important for receptor binding. The fe...
متن کاملEnterobactin-Mediated Delivery of β-Lactam Antibiotics Enhances Antibacterial Activity against Pathogenic Escherichia coli
The design, synthesis, and characterization of enterobactin-antibiotic conjugates, hereafter Ent-Amp/Amx, where the β-lactam antibiotics ampicillin (Amp) and amoxicillin (Amx) are linked to a monofunctionalized enterobactin scaffold via a stable poly(ethylene glycol) linker are reported. Under conditions of iron limitation, these siderophore-modified antibiotics provide enhanced antibacterial a...
متن کاملBinding of ferric enterobactin by the Escherichia coli periplasmic protein FepB.
The periplasmic protein FepB of Escherichia coli is a component of the ferric enterobactin transport system. We overexpressed and purified the binding protein 23-fold from periplasmic extracts by ammonium sulfate precipitation and chromatographic methods, with a yield of 20%, to a final specific activity of 15,500 pmol of ferric enterobactin bound/mg. Periplasmic fluid from cells overexpressing...
متن کاملSelectivity of ferric enterobactin binding and cooperativity of transport in gram-negative bacteria.
The ligand-gated outer membrane porin FepA serves Escherichia coli as the receptor for the siderophore ferric enterobactin. We characterized the ability of seven analogs of enterobactin to supply iron via FepA by quantitatively measuring the binding and transport of their 59Fe complexes. The experiments refuted the idea that chirality of the iron complex affects its recognition by FepA and demo...
متن کاملCatechol Siderophore Transport by Vibrio cholerae.
UNLABELLED Siderophores, small iron-binding molecules secreted by many microbial species, capture environmental iron for transport back into the cell. Vibrio cholerae synthesizes and uses the catechol siderophore vibriobactin and also uses siderophores secreted by other species, including enterobactin produced by Escherichia coli. E. coli secretes both canonical cyclic enterobactin and linear e...
