Journal ArticleDOI
Bacterial iron homeostasis
TL;DR: The expression of the iron homeostatic machinery is subject to iron-dependent global control ensuring that iron acquisition, storage and consumption are geared to iron availability and that intracellular levels of free iron do not reach toxic levels.
Journal ArticleDOI
Opening the Iron Box: Transcriptional Metalloregulation by the Fur Protein
TL;DR: It is generally accepted that iron is the most important micronutrient used by bacteria, but this element is not easily available to microorganisms in aerobic environments, so iron uptake has to be exquisitely regulated to maintain the intracellular concentration of the metal between desirable limits.
Journal ArticleDOI
Traits of fluorescent Pseudomonas spp. involved in suppression of plant root pathogens.
TL;DR: The understanding of the relevant characteristics will facilitate the direct selection and/or construction of strains which will perform under a variety of environmental conditions, and facilitate attempts aimed at the improvement of strains based on deregulating pathways or introducing traits from one strain to another.
Journal ArticleDOI
Ferric uptake regulation protein acts as a repressor, employing iron (II) as a cofactor to bind the operator of an iron transport operon in Escherichia coli.
Anne Bagg,J. B. Neilands +1 more
TL;DR: The results support the hypothesis that prokaryotic cells may contain a standing pool of free or loosely bound Fe(II) that is capable of acting in a regulatory capacity and conclude that Fur acts as a classical negative repressor that, under in vivo conditions, uses ionic Fe( II) as a corepressor.
Journal ArticleDOI
Lack of a Role for Iron in the Lyme Disease Pathogen
TL;DR: The Lyme disease pathogen Borrelia burgdorferi has bypassed this host defense by eliminating the need for iron by growing normally and altering gene expression in the presence of iron chelators.

Iron-Binding Catechols and Virulence in Escherichia coli.
TL;DR: Time studies indicated that leukemic and nonleukemic viruses caused similar patterns in the alteration of PHA-induced DNA synthesis, whereas lactic dehydrogenase virus, adenovirus, and polyoma virus induced an increase in DNA synthesis.

Manganese and Defenses against Oxygen Toxicity in Lactobacillus plantarum
TL;DR: This organism was comparable to superoxide dismutase-containing species in its resistance toward hyperbaric O(2) and toward the oxygen-dependent lethality of plumbagin and appeared to use millimolar levels of Mn(II) to scavenge O(1) (-)-scavenging, much as most other organisms use micromolar Levels of superoxide Dismutases.
