Genomics of Acinetobacter baumannii iron uptake. [PDF]

Microb Genom, 2023
Iron is essential for growth in most bacteria due to its redox activity and its role in essential metabolic reactions; it is a cofactor for many bacterial enzymes. The bacterium Acinetobacter baumannii is a multidrug-resistant nosocomial pathogen.

High Affinity Iron Acquisition Systems Facilitate but Are Not Essential for Colonization of Chickens by Salmonella Enteritidis

Frontiers in Microbiology, 2022
The roles of TonB mediated Fe3+ (ferric iron) uptake via enterobactin (involving biosynthesis genes entABCDEF) and Fe2+ (ferrous iron) uptake through the FeoABC transporter are poorly defined in the context of chicken-Salmonella interactions. Both uptake

Plasmid-Encoded Iron Uptake Systems [PDF]

Microbiology Spectrum, 2014
ABSTRACT Plasmids confer genetic information that benefits the bacterial cells containing them. In pathogenic bacteria, plasmids often harbor virulence determinants that enhance the pathogenicity of the bacterium. The ability to acquire iron in environments where it is limited, for instance the eukaryotic host, is a critical factor for ...

Regulation of brain iron uptake by apo- and holo-transferrin is dependent on sex and delivery protein

Fluids and Barriers of the CNS, 2022
Background The brain requires iron for a number of processes, including energy production. Inadequate or excessive amounts of iron can be detrimental and lead to a number of neurological disorders. As such, regulation of brain iron uptake is required for

Iron Uptake by Fungi Isolated from Arcelor Mittal -Annaba- in the Northeast of Algeria [PDF]

Brazilian Journal of Poultry Science, 2021
The Metal pollution is one of the major risks in the world nowadays. Iron is an essential metal for growth and proliferation of a vast majority of organisms, but it can be toxic to human health and other living beings in the environment at high ...

Ferredoxin containing bacteriocins suggest a novel mechanism of iron uptake in Pectobacterium spp [PDF]

, 2012
In order to kill competing strains of the same or closely related bacterial species, many bacteria produce potent narrow-spectrum protein antibiotics known as bacteriocins.

Deregulated High Affinity Copper Transport Alters Iron Homeostasis in Arabidopsis

Frontiers in Plant Science, 2020
The present work describes the effects on iron homeostasis when copper transport was deregulated in Arabidopsis thaliana by overexpressing high affinity copper transporters COPT1 and COPT3 (COPTOE).
