The advent of O2 in the atmosphere was among the first major pollution events occurred on
earth. The reaction between ferrous iron, very abundant in the reductive early atmosphere …

One of the strongest and most noticeable responses of a Bacillus subtilis cell to a range of
stress and starvation conditions is the dramatic induction of a large number of general stress …

The aim of this study was to critically analyze the effects of hydrogen peroxide on growth and
survival of bacterial cells in order to prove or disprove its purported role as a main …

Fur (ferric uptake regulator) proteins control iron uptake in many Gram‐negative bacteria.
Although Fur homologues have been identified in Gram‐positive bacteria, their roles in gene …

Bacillus subtilis exhibits a complex adaptive response to low levels of peroxides. We used
global transcriptional profiling to monitor the magnitude and kinetics of changes in the …

Bacillus subtilis displays a complex adaptive response to the presence of reactive oxygen
species. To date, most proteins that protect against reactive oxygen species are members of …

The inducible response to H2O2 stress in Bacillus subtilis is under the control of PerR, one
of three Fur homologues in this organism. PerR was purified in both an inactive, metal …

Bacillus subtilis cells respond almost immediately to different stress conditions by increasing
the production of general stress proteins (GSPs). The genes encoding the majority of the …

The Bacillus subtilis mrgA gene encodes an abundant DNA-binding protein that protects
cells against the lethal effects of H2O2. Transcription of mrgA is induced by H2O2 or by entry …

PerR is a ferric uptake repressor (Fur) homolog that functions as the central regulator of the
inducible peroxide stress response in Bacillus subtilis. PerR has been previously …
