Influence of Bacillus subtilis phoR on cell wall anionic polymers
Article Abstract:
The functional roles of the Pho regulon PhoR and PhoP regulators of Bacillus subtilis on cell wall anionic polymers were analyzed to determine the mechanisms of teichuronic acid biosynthesis. Analysis of Bacillus subtilis PhoR and PhoP regulons indicated the role of the phosphate regulon for survival in extreme environments involving phosphate starvation. Furthermore, the induction of genes in the Pho regulon during phosphate starvation was regulated by a second unidentified phosphate-sensing mechanism.

The yvsA-yvqA (293 degrees-289 degrees) region of the Bacillus subtilis chromosome containing genes involved in metal ion uptake and a putative sigma factor
Article Abstract:
A study was conducted to examine the yvsA-yvqA region of the Bacillus subtilis chromosome which supports genes associated with metal ion uptake and a putative sigma factor. DNA fragments were determined by random primed labeling using the Rediprime system while pUC18 clones were prepared by universal forward and reverse primers. Results indicated that the yvrC, yvrB, yvrA and yvqK genes were arranged in an operon of 3.9 kb in size encoding another putative transporter.
