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.
