* Cyclic di-AMP is an essential second messenger in ''B. subtilis'' and other Gram-positive bacteria. This molecule has been discovered only in 2008, and a lot of work has recently been devoted to the investigation of its function. This month, [http://www.ncbi.nlm.nih.gov/pubmed/24141192 Nelson et al.] from the lab of [[Ronald Breaker]] discovered that c-di-AMP binds to the [[ydaO riboswitch]]. This is extremely interesting since the molecule does also bind the [[KtrA]] potassium transporter. The ''[[ktrA]]-[[ktrB]]'' operon is also controlled by a [[ydaO riboswitch]]. Thus c-di-AMP is the first signalling nucleotide that controls a biological process by binding both a protein and the encoding mRNA.

* Intercellular signaling requires the transfer of information between two different cells. Now, [http://www.ncbi.nlm.nih.gov/pubmed/24243021 Mastny et al.] from the labs of [[David Rudner]] and Tim Clausen show how the protease [[CtpB]] is activated by substrate binding to cleave off the inhibitory domain of [[SpoIVFA]] to allow ultimately allow processing of pro-[[SigK]] by [[SpoIVFB]].

Paper of the month: December 2013


New procedure for account creation:

  • Due to massive spam attacks, we had to change our policy for the creation of accounts. If you want to create an account, just send me a mail. We will create the account for you as quickly as possible, then you can change your password. This does not affect existing accounts, which remain active.
  • Please remember that all members of the Bacillus community are invited to create accounts and to contribute to SubtiWiki!



News in SubtiWiki:

  • April 2013: SubtiWiki uses a new, faster Mediawiki platform! The times for page access are significantly reduced. Enjoy!
  • March 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.
