Paper of the month: June 2014

  • Transcription by RNA polymerase is interrupted by pauses that play diverse regulatory roles. However, the determinants of pauses in vivo and their distribution throughout the bacterial genome remain unknown. Using nascent transcript sequencing, Larson et al. identified a 16-nucleotide consensus pause sequence. The pauses result from RNA polymerase-nucleic acid interactions that inhibit next-nucleotide addition. The consensus sequence is enriched at translation start sites in Bacillus subtilis.

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
