Yersiniabactin reduces the respiratory oxidative stress response of innate immune cells. [PDF]
PLoS ONE, 2009 Enterobacteriaceae that contain the High Pathogenicity Island (HPI), which encodes the siderophore yersiniabactin, display increased virulence. This increased virulence may be explained by the increased iron scavenging of the bacteria, which would both ...

FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Revista de Metalurgia, 2023 Turkey’s iron ores may be used to manufacture sponge iron, and the country’s coal resources, which are plentiful despite being of poor quality, can be used as a reducing agent. With such a production, Electric Arc Furnace based on scrap imports, will be

FEBS Letters, EarlyView.The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Toward Decarbonization of the Titanium Industry via Hydrogen Plasma Smelting Reduction
Advanced ScienceSurging global demand for titanium, driven by its essential role in aerospace, transportation, chemical industries, and as a white pigment, is intensifying pressure on scarce high‐grade ores, like rutile, leading to their rapid depletion.

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
