New: Website of the month: June 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.

Paper of the month: June 2013

• DNA transfer across membranes is important in many fundamental processes. However, the molecular mechanisms behind this transport are only poorly understood. Now, Fiche et al. analysed the assembly and molecular architecture of the SpoIIIE DNA translocation complex. This study reveals that in contrast to previous model, DNA transfer occurs through an aqueous DNA-conducting pore that could be structurally maintained by the divisional machinery, with SpoIIIE acting as a checkpoint preventing membrane fusion until completion of chromosome segregation.

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.
