For cured meat products, nitrite is recognized for its antimicrobial effects against pathogenic
bacteria, even though the specific inhibitory mechanisms are not well known. Nitrite …

Escherichia coli is equipped with multiple systems to ensure safe copper handling under
varying environmental conditions. The Cu (I)-translocating P-type ATPase CopA, the central …

This work investigates the role of oxidation state in the antibacterial activity of copper oxide
nanoparticles (NPs). The findings add strong support to a contact killing mechanism of …

Using a genetic screen we have identified two chromosomal genes, cusRS (ylcA ybcZ), from
Escherichia coli K-12 that encode a two-component, signal transduction system that is …

RNA-interference (RNAi) is a potent mechanism, conserved from plants to humans for
specific silencing of genes, which holds promise for functional genomics and gene-targeted …

This study assesses whether the phylogenetic relationships between SODs from different
organisms could assist in elucidating the functional relationships among these enzymes …

Staphylococcus aureus has two superoxide dismutases (SODs), encoded by the sodA and
sodM genes, which inactivate harmful superoxide radicals () encountered during host …

Superoxide dismutase (SOD) is a crucial enzyme required to maintain the redox potential of
the cells. It plays a vital role in protecting normal cells from reactive oxygen species (ROS) …

Neisseria gonorrhoeae is a host-adapted pathogen that colonizes primarily the human
genitourinary tract. This bacterium encounters reactive oxygen and reactive nitrogen species …

Brucellosis is characterized by abortion in ruminants and a protracted undulant fever in
humans, which often results in severe pathological manifestations. Scant information exists …
