Paper of the month: May 2015
- In B. subtilis, ribosomal stalling is used to regulate the expression of the membrane protein biogenesis factor YidC2. This is achieved by stalling during translation of the MifM leader peptide. In the absence of structures of Gram-positive bacterial ribosomes, a molecular basis for species-specific stalling has remained unclear. Sohmen et al. have determined the structure of the MifM-stalled 70S ribosome and have unraveled a network of interactions between MifM and the ribosomal tunnel, which induces translational arrest. Complementary genetic analyses identify a single amino acid within ribosomal protein L22 that dictates the species specificity of the stalling event.
- Relevant SubtiWiki pages: translation, ribosome, yidC2, MifM, L22
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
