The Bacillus subtilis ureABC operon [PDF]
Journal of Bacteriology, 1997 The Bacillus subtilis ureABC operon encodes homologs of the three subunits of urease enzymes of the family Enterobacteriaceae. Disruption of ureC prevented utilization of urea as a nitrogen source and resulted in a partial growth defect in minimal medium containing limiting amounts of arginine or allantoin as the sole nitrogen source.

Stochastic model for Soj relocation dynamics in Bacillus subtilis [PDF]
Proc. Natl. Acad. Sci. 102 9808-9813 (2005), 2005 The Bacillus subtilis Spo0J/Soj proteins, implicated in chromosome segregation and transcriptional regulation, show striking dynamics: Soj undergoes irregular relocations from pole to pole or nucleoid to nucleoid. Here we report on a mathematical model of the Soj dynamics.

High-salinity growth conditions promote tat-independent secretion of tat substrates in Bacillus subtilis [PDF]
, 2012 The Gram-positive bacterium Bacillus subtilis contains two Tat translocases, which can facilitate transport of folded proteins across the plasma membrane. Previous research has shown that Tat-dependent protein secretion in B.

Survival of thermophilic spore-forming bacteria in a 90+ year old milk powder from Ernest Shackelton's Cape Royds Hut in Antarctica [PDF]
, 2000 Milk powder taken to Antarctica on Shackelton's British Antarctic Expedition in 1907 was produced in New Zealand by a roller drying process in the first factory in the world dedicated to this process. Thermophilic bacilli are the dominant contaminants of

The motility-matrix production switch in Bacillus subtilis -- a modeling perspective [PDF]
arXiv, 2023 Phenotype switching can be triggered by external stimuli and by intrinsic stochasticity. Here, we focus on the motility-matrix production switch in Bacillus subtilis. We use modeling to describe the SinR-SlrR bistable switch its regulation by SinI, and to distinguish different sources of stochasticity.

Calcium signalling in Bacillus subtilis
Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 1998 Few systematic studies have been devoted to investigating the role of Ca2+ as an intracellular messenger in prokaryotes. Here we report an investigation on the potential involvement of Ca2+ in signalling in Bacillus subtilis, a Gram-positive bacterium. Using aequorin, it is shown that B. subtilis cells tightly regulate intracellular Ca2+ levels.
