[[http://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>  [[http://www.uniprot.org/uniprot/RPOA_BACSU RPOA_BACSU]] DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
