Paper of the month: July 2014
- T-boxes are regulatory mRNA elements which sense amino acid availability and control the expression of genes encoding aminoacyl-tRNA synthetases and biosynthetic enzymes. Sensing is thought to occur by the interaction of the uncharged tRNA with the T-box thus preventing the formation of a transcription terminator. It has however, not been known whether this regulation involves proteins. Now, Zhang and Ferre-D'Amare show that the B. subtilis glyQ-glyS T-box functions independently of any tRNA-binding protein. They demonstrate that the T-box detects the molecular volume of tRNA 3'-substituents..

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
