E-0702, a new cephalosporin with a potent antipseudomonal action, was synthesized. In the study of the mode of action of this antibiotic in Escherichia coli, it was found that mutants which acquired resistance to E-0702 were isolated spontaneously and could be shown to be susceptible to its closely related derivatives, E-0702-060 and E-0702-061, and other representative beta-lactam antibiotics. In these mutants, no increased production of beta-lactamase was detectable. No apparent differences… 
Mechanism of tonB-dependent transport of KP-736, a 1,5-dihydroxy-4-pyridone-substituted cephalosporin, into Escherichia coli K-12 cells
TLDR
Results indicate that the Cir and Fiu outer membrane proteins are involved specifically in the tonB-dependent transport process of KP-736, and against OmpF- and OmpC-deficient transformants producing various groups of beta-lactamases, KP-756 was more effective than the other cephalosporins tested.
Comparison of transport pathways of catechol-substituted cephalosporins, BO-1236 and BO-1341, through the outer membrane of Escherichia coli.
TLDR
The diversity of the transport pathway as assessed from the characterization of spontaneous mutants of E. coli selected with BO-1236 and BO-1341 is reported, and the influence of bacterial growth under anaerobic condition and in the presence of ascorbic acid as well as iron concentration in the medium, on the antibacterial activity of these catechol-substituted cephalosporins is noted.
Genetic definition of the substrate selectivity of outer membrane porin protein OprD of Pseudomonas aeruginosa
TLDR
The results clearly demonstrated that OprD could be utilized by imipenem and meropenem but that, even when substantially overexpressed, it could not be significantly utilized by other beta-lactams, quinolones, or aminoglycosides.
Enterobactin-Mediated Delivery of β-Lactam Antibiotics Enhances Antibacterial Activity against Pathogenic Escherichia coli
TLDR
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 enterobactsin scaffold via a stable poly(ethylene glycol) linker are reported provide enhanced antibacterial activity against Escherichia coli strains under conditions of iron limitation.
Identification and characterization of the exbB, exbD and tonB genes of Pseudomonas putida WCS358: their involvement in ferric‐pseudobactin transport
TLDR
It is concluded that P. putida WCS358 contains an energy‐coupling system between the membranes for active transport across the outer membrane, which is comprised of a TonB‐like energy‐transducing protein and two accessory proteins, similar to, but not completely compatible with, the E. coli system.
Cir and Fiu proteins in the outer membrane of Escherichia coli catalyze transport of monomeric catechols: study with beta-lactam antibiotics containing catechol and analogous groups
TLDR
It is shown that the wild-type cells transported unliganded E0702 at a rate comparable to or even higher than the rate of transport of the E0701-Fe3+ complex, and postulate that the main function of Cir and Fiu may be to recapture the hydrolytic products of enterobactin, such as 2,3-dihydroxybenzoylserine.
Involvement of the TonB System in Tolerance to Solvents and Drugs in Pseudomonas putida DOT-T1E
TLDR
The mutant DOT-T1E-PhoA5 strain, which was more sensitive than the wild type to 4HBA and toluene, and its growth in iron-deficient minimal medium was inhibited in the presence of ethylenediamine-di(o-hydroxyphenylacetic acid (EDDHA).
Ferric iron transport system of Pseudomonas aeruginosa PAO1 that functions as the uptake pathway of a novel catechol-substituted cephalosporin, S-9096
TLDR
Results indicated that the ferric chelate of S-9096 was incorporated into P. aeruginosa cells via a ferric iron transport pathway, which caused the high antibacterial potency of S -9096.
In vitro and in vivo activities of LB10522, a new catecholic cephalosporin
TLDR
Time-kill study showed that LB10522, at concentrations of two or four times the MIC, had a rapid bactericidal activity against Staphylococcus aureus 6538p, Escherichia coli 851E, and Pseudomonas aeruginosa 1912E.
In vitro and in vivo evaluation of Ro 09-1428, a new parenteral cephalosporin with high antipseudomonal activity
TLDR
The results indicate that Ro 09-1428 is a broad-spectrum cephalosporin with advantages over ceftazidime in its activity against P. aeruginosa, staphylococci, and ceftrazidime-resistant strains of C. freundii and E. cloacae.

Relationship between the tonB locus and iron transport in Escherichia coli
TLDR
The evidence suggests that tonB- strains lack an outer membrane component necessary both for the uptake of ferric-enterochelin and for the adsorption of phage phi80, suggesting that the known active transport systems for iron may share some common external membrane component.
Outer membrane permeation of beta-lactam antibiotics in Escherichia coli, Proteus mirabilis, and Enterobacter cloacae
TLDR
The results suggested that the main pathway for cephalosporin permeation is the pore made up of these proteins, and it was suggested that ampicillin and other penicillins possess another unknown route for outer membrane permeation.
Iron transport of Escherichia coli K-12: involvement of the colicin B receptor and of a citrate-inducible protein
It was shown that feuB mutants (defective in ferric enterochelin uptake) were unable to adsorb colicin B. In addition, they were missing one of the three outer-membrane proteins which are over
Triornithine-resistant strains of Escherichia coli. Isolation, definition, and genetic studies.
TLDR
Triornithine-resistant (TOR) mutants were isolated from several strains of Escherichia coli K-12 and found to be oligopeptide transport-deficient (Opp-), finding the opp gene is the closest marker to the trp operon.
Escherichia coli cells containing the plasmid ColV produce the iron ionophore aerobactin
TLDR
It is reported that aerobactin is the new iron ligand produced by ColV-bearing E. coli strains, guided by the fact that other Enterobacteriaceae, Aerobacter aerogenes, Shigella flexneri and Enterobacteria cloacae produce aerobACTin.
Characterization of group B colicin-resistant mutants of Escherichia coli K-12: colicin resistance and the role of enterochelin
TLDR
Nine classes of group B colicin-resistant mutants were examined and four of the mutants studied hypersecreted enterochelin, apparently responsible for resistance of the exbC mutant to colicins G and H and for Resistance of theExbB mutant to Colicin G, Ia, Ib, S1, and V.
Porin channels in Escherichia coli: studies with beta-lactams in intact cells
TLDR
The properties of the PhoE porin are consistent with the recent finding that its biosynthesis is derepressed by phosphate starvation; the channel may thus act as an emergency pore primarily for the uptake of phosphate and phosphorylated compounds.
An additional step in the transport of iron defined by the tonB locus of Escherichia coli.
TLDR
Also involved in the uptake of iron is an energy-dependent component which can be demonstrated by treatment of wild type or tonB- cells with azide and iodoacetamide and the energy poisons decrease the Vmax of iron accumulation by approximately 10-fold, but they do not alter the apparent Km.
Functional Interaction of the tonA/tonB Receptor System in Escherichia coli
TLDR
There exist different functional states of the receptor protein that depend on the energy state of the cell and the tonB function, and the latter seems to be required only for translocation processes with outer membrane proteins involved.
Functional stability of the bfe and tonB gene products in Escherichia coli
TLDR
Receptors that were no longer functional for colicin or phage uptake remained fully effective for B12 uptake, showing that receptors are stable on the cell surface, and supports previous contentions for the presence of different functional states for Colicin receptors.
