| + | [https://www.uniprot.org/uniprot/SPX_BACSU SPX_BACSU] Interferes with activator-stimulated transcription by interaction with the RNA polymerase alpha-CTD. May function to globally reduce transcription of genes involved in growth- and development-promoting processes and to increase transcription of genes involved in thiol homeostasis, during periods of extreme stress. Negatively affects competence and sporulation. Its degradation by the MecA/ClpXP complex is needed for competence development.<ref>PMID:11703662</ref> <ref>PMID:12642660</ref>   | ||

| + | == Publication Abstract from PubMed ==  | ||
| + | The Bacillus subtilis Spx protein is a global transcription factor that interacts with the C-terminal domain of the RNA polymerase alpha subunit (alphaCTD) and regulates transcription of genes involved in thiol-oxidative stress, sporulation, competence, and organosulfur metabolism. Here we determined the X-ray crystal structure of the Spx/alphaCTD complex from an entirely new crystal form than previously reported [Newberry, K.J., Nakano, S., Zuber, P., Brennan, R.G., 2005. Crystal structure of the Bacillus subtilis anti-alpha, global transcriptional regulator, Spx, in complex with the alpha C-terminal domain of RNA polymerase. Proc. Natl. Acad. Sci. USA 102, 15839-15844]. Comparison of the previously reported sulfate-bound complex and our sulfate-free complex reveals subtle conformational changes that may be important for the role of Spx in regulating organosulfur metabolism.  | ||
