The Bacillus subtilis extracytoplasmic function sigma factor σY is of unknown function. We
demonstrate that the sigY operon is expressed from an autoregulatory promoter site, PY. We …

A novel facultative thermophilic bacterium capable of producing rare ketoses from polyols
was isolated from soil and identified as Bacillus pallidus Y25. We have employed this …

The Bacillus subtilis 168 genome contains an array of alternative σ factors, many of which
play important roles in reprogramming expression during stress and sporulation. The role of …

High cell density cultivations were performed under identical conditions for two Bacillus
megaterium strains (MS941 and WH320), both carrying a heterologous dextransucrase …

We investigated the organization and expression of the Bacillus subtilis sigY operon, the first
gene of which codes for σY, a member of the extracytoplasmic function (ECF) family of sigma …

The HspR protein functions as a negative regulator of chaperone and protease gene
expression in a diversity of bacteria. Here we have identified, cloned and deleted the …

The Bacillus subtilis global regulator AbrB was found to negatively control expression of
sigW and genes of the σW regulon. AbrB bound to DNA regions in the autoregulatory sigW …

Bacteria continually modulate gene expression in response to changing environmental
conditions. Although many transcription regulatory pathways respond to internal signal …

Bacillus subtilis phosphorylates sugars during or after their transport into the cell.
Perturbation in the conversion of intracellular phosphosugars to the central carbon …

ABSTRACT β-Exotoxin I is an insecticidal nucleotide analogue secreted by various Bacillus
thuringiensis strains. In this report, we describe the characterization and transcriptional …
