Investigation of lysine: N-hydroxylation in the biosynthesis of the siderophore aerobactin

Bioorganic Chemistry, 1989
Abstract N -Ethylmaleimide was found to inhibit both pyruvate oxidation and lysine: N 6 -hydroxylation catalyzed by an enzyme system derived from Aerobacter aerogenes 62-1. Studies of pyruvate utilization in the presence and absence of lysine indicated a 1:1 stoichiometric relationship between consumption of pyruvate and production of N 6 ...

The Plasmid-Specified Aerobactin Iron Uptake System of Escherichia Coli

1985
Escherichia coli is a major aerobic commensal bacterial species in the intestinal flora of a healthy individual. Some strains, however, are pathogenic for man, causing disease by a variety of mechanisms, and with a severity that ranges from the temporary, if acute, discomfort of “turista” to the chronic human tragedy of widespread infant mortality in ...

Identification of the genes and their polypeptide products responsible for aerobactin synthesis by pColV plasmids

Molecular and General Genetics MGG, 1985
Iron acquisition via aerobactin enhances the virulence of Escherichia coli. Genes that specify functions for aerobactin synthesis and iron(III)-aerobactin transport have been identified on several ColV plasmids. Previously, we cloned the locus for aerobactin synthesis from pColV-K311 and assigned to three loci termed aerA, aerB, and aerC the functions ...

Photoreactivity of Iron(III)−Aerobactin:  Photoproduct Structure and Iron(III) Coordination

Inorganic Chemistry, 2006
UV photolysis of the ferric aerobactin complex results in decarboxylation of the alpha-hydroxy carboxylic acid group of the central citrate moiety of aerobactin. The structure determination of the photooxidized ligand shows that decarboxylation occurs at the citrate moiety forming a 3-ketoglutarate moiety.

Aerobactin production of serotyped Escherichia coli from urinary tract infections

Medical Microbiology and Immunology, 1987
Aerobactin production was examined by a bioassay in 467 Escherichia coli urinary strains from girls. All strains were of known O:K:H serotype. 139, 119 and 112 strains were isolates from pyelonephritis (Py), cystitis (Cy) and asymptomatic bacteriuria (ABU), respectively, and 97 were from fecal samples of healthy girls (FN).

[Bioassay for the detection of hydroxamate-iron-chelators (Aerobactin)].

Journal of basic microbiology, 1986
Different Salmonella strains were tested for aerobactin production in a hydroxamate-bioassay with the aerobactin indicator strain E. coli LG 1522. The majority of hospital strains of Salmonella typhimurium produce hydroxamate siderophore. On the other hand S. typhimurium strains belonging to phage type n. c. 1/72/n.

Photodissolution of lepidocrocite (γ-FeOOH) in the presence of desferrioxamine B and aerobactin

Geochimica et Cosmochimica Acta, 2009
Abstract Batch adsorption and dissolution experiments with lepidocrocite (γ-FeOOH) and two siderophores, desferrioxamine B (DFOB) and aerobactin, were performed between pH 3 and 8 in the dark and under irradiation with UV–visible light. The increase in surface concentrations of adsorbed DFOB with increasing pH was explained in terms of electrostatic ...

Influence of monosaccharides on aerobactin production byAerobacter aerogenes 62-1

Current Microbiology, 1987
Supplementation of cultures ofAerobacter aerogenes 62-1, 43/4 h after initiation of growth withd-glucose (20 mM), resulted in a threefold increase in the production of aerobactin. Administration ofl-lysine under similar conditions led to a twofold incrasse in the yield of the siderophore.
