* For many [[essential genes]] of ''B. subtilis'', it is not clear why they are essential in ''B. subtilis'' but not in closely related species. Strikingly, this is the case for [[RNases]] such as RNases [[rnc|III]] and [[rny|Y]]. Now, [http://www.ncbi.nlm.nih.gov/pubmed/23300471 Durand et al..] from the lab of [[Ciaran Condon]] have identified the reason for the essentiality of [[rnc|RNase III]]: This enzyme is required to degrade phage encoded toxin mRNA molecules thus protecting the cell from lysis caused by the encoded toxins. Indeed, [[rnc|RNase III]] is dispensable in a strain lacking the [[Skin element]] and the [[SPß prophage]] that harbor the corresponding toxin genes.

News in SubtiWiki:

  • January 2013: updated Excel files that map all genes to categories and regulons as well as the general updated identity mapping of all genes were uploaded.
  • October 2012: the essential genes have been categorized
  • September 2012: 300 mutant strains available at the BGSC were added to the corresponding gene pages
  • August 2012: SubtiExpress, the new compagnon of SubtiWiki devoted to gene expression is online! Try it out!
  • April 2012: Links for expression data under 104 different conditions (based on Nicolas et al., 2012) have been added to the expression section of the individual gene pages
  • April 2011: SubtInteract, a presentation of protein-protein interactions in B. subtilis, is online!
  • December 2010: SubtiCellPublisher allows the conversion of CellDesigner diagrams to navigatable presentations in the style of SubtiPathways
  • December 2010: all genes are linked to regulons, and the pages of the regulons provide an overview on all genes that are members of this specific regulon.
  • December 2010: all genes/proteins are linked to categories, and the pages of the categories provide an overview on all genes/proteins that are members of this specific category.
