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.

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 ...

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 ...

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).

Mining iron: Iron uptake and transport in plants [PDF]
FEBS Letters, 2007 Iron uptake in plants is highly regulated in order to supply amounts sufficient for optimal growth while preventing excess accumulation. In response to iron deficiency, plants induce either reduction‐based or chelation‐based mechanisms to enhance iron uptake from the soil.

Iron Uptake Mechanisms in Marine Phytoplankton [PDF]
Frontiers in Microbiology, 2020 Oceanic phytoplankton species have highly efficient mechanisms of iron acquisition, as they can take up iron from environments in which it is present at subnanomolar concentrations. In eukaryotes, three main models were proposed for iron transport into the cells by first studying the kinetics of iron uptake in different algal species and then, more ...

Salmonella Facilitates Iron Acquisition through UMPylation of Ferric Uptake Regulator
mBio, 2022 Iron limitation is a universal strategy of host immunity during bacterial infection. However, the mechanisms by which pathogens antagonize host nutritional immunity have not been fully elucidated.
