* In ''Bacillus subtilis'', [[glutamate metabolism|nitrogen acquisition]] is controlled by [[SubtInteract|protein-protein interactions]]. Regulation is brought about by [[SubtInteract|interactions]] of the [[trigger enzyme|trigger enzymes]] [[GlnA|glutamine synthetase]] with the transcription factors [[TnrA]] and [[GlnR]] to inhibit or trigger their DNA-binding activity, respectively, and by the PII protein [[NrgB]] that also interacts with [[TnrA]]. Now, [http://www.ncbi.nlm.nih.gov/pubmed/25691471 Schumacher et al.] have solved the structures of several complexes involved in nitrogen sensing. The results unravel so far unprecendented mechanisms for metabolic reprogramming of the cell in response to nitrogen availability.

* In a [http://www.ncbi.nlm.nih.gov/pubmed/15096624 groundbreaking study from 2004], several candidate [[riboswitch]]es have been discovered in ''Bacillus subtilis''. While the [[ydaO riboswitch]] has recently been discovered to be a target of the second messenger c-di-AMP, two new studies identify manganese ions as the ligand of the [[yybP-ykoY motif]] that controls the expression of the ''[[yybP]]'' and ''[[ykoY]]'' genes. Both genes are induced in the presence of Mn<sup>2+</sup>, due to the interaction of the ion with the [[riboswitch]]. This finding implies that [[YybP]] and [[YkoY]], which have not yet been functionally studied, are implicated in the control of manganese homeostasis.

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:

  • August 2014: The first mobile application for SubtiWiki is now available for users of Android phones: Go for SubtiWiki in Google Play! IPhone users, please be patient! You will be served next! Click here to install!
  • 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
