Biofilms are surface-associated, multicellular communities of bacteria. Once established,
they are extremely difficult to eradicate by antimicrobial treatment. It has been demonstrated …

Under a shortage of oxygen, bacterial growth can be faced mainly by two ATP-generating
mechanisms:(i) by synthesis of specific high-affinity terminal oxidases that allow bacteria to …

Abstract Iron–sulfur (Fe–S) cluster containing proteins that regulate gene expression are
present in most organisms. The innate chemistry of their Fe–S cofactors makes these …

Nitrous oxide (N 2 O) is an important greenhouse gas (GHG) with substantial global
warming potential and also contributes to ozone depletion through photochemical nitric …

Rickettsia peacockii, also known as the East Side Agent, is a non-pathogenic obligate
intracellular bacterium found as an endosymbiont in Dermacentor andersoni ticks in the …

Summary The Escherichia coli NsrR protein is a nitric oxide‐sensitive repressor of
transcription. The NsrR‐binding site is predicted to comprise two copies of an 11 bp motif …

Molecular oxygen (O2) and nitric oxide (NO) are diatomic gases that play major roles in
infection. The host innate immune system generates reactive oxygen species and NO as …

Nitric oxide (NO) is a toxic, free radical gas with diverse biological roles in eukaryotes and
bacteria, being involved in signalling, vasodilation, blood clotting and immunity and as an …

The Rrf2 family transcription factor NsrR controls expression of genes in a wide range of
bacteria in response to nitric oxide (NO). The precise form of the NO-sensing module of …

Iron-binding transcription factors are widespread throughout the bacterial world and to date
are known to bind several types of cofactors, such as Fe2+, heme, or iron–sulfur clusters …
