Paper of the month: July 2013
- Ca(2+) efflux by Ca(2+) cation antiporter (CaCA) proteins is important for maintenance of Ca(2+) homeostasis across the cell membrane. Now, Wu et al. determined the structure of the B. subtilis Ca(2+)/H(+) antiporter protein ChaA. By structural and mutational analyses, they establish structural bases for mechanisms of Ca(2+)/H(+) exchange and its pH regulation. Moreover, this work also sheds light on the evolutionary adaptation to different energy modes in the CaCA protein family.

New: Website of the month: July 2013: SporeWeb
- SporeWeb is a dynamic web-based platform describing all stages of sporulation in B. subtilis from a gene regulatory point of view. The website is intended for all microbial researches interested in bacterial sporulation and/or gene regulatory networks and contains useful information for both sporulation experts and non-experts.
- You can find:
- detailed review-like descriptions of all sporulation stages,
- schematic representations of regulatory events during every stage,
- links to specific regulators and their regulons,
- access to detailed Excel sheets of all sporulation-specific regulons,
- Cytoscape-generated layouts of regulon interactions during a specific stage,
- a tool to generate your own Cytoscape interaction figure for specific genes of interest,
- heat maps showing expression values of all sporulation genes during the sporulation cycle (derived from Nicolas et al., 2012),
- direct links to other knowledge platforms, such as SubtiWiki,
- an extensive list of references for further detailed information.
- The website is self explanatory, but you can also take a quick look at the short introduction video.
- Importantly, the website is database driven: it can (and will) be updated as new exciting insights become available in literature.
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.
