* [[T-box]]es are regulatory mRNA elements which sense amino acid availability and control the expression of genes encoding aminoacyl-tRNA synthetases and biosynthetic enzymes.

Paper of the month: August 2014

  • Calcium is important for the activity of many many enzymes, and its cellular homeostasis is therefore important. Now, the previously unknown YetJ protein has been identified as a pH-sensitive calcium leak that allows reducing the inracellular calcium concentration. Chang et al. report the structure of YetJ and explain how two conserved Asp residues sense changes in the pH.

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
