+== Function ==
+[[http://www.uniprot.org/uniprot/K0BU55_ECO1E K0BU55_ECO1E]] Promotes RNA polymerase assembly. Latches the N- and C-terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits.[HAMAP-Rule:MF_00366][SAAS:SAAS00054255] [[http://www.uniprot.org/uniprot/B1X6E7_ECODH B1X6E7_ECODH]] DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.[HAMAP-Rule:MF_00059] [[http://www.uniprot.org/uniprot/K0BCS5_ECO1E K0BCS5_ECO1E]] DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.[HAMAP-Rule:MF_01322][SAAS:SAAS00054030] [[http://www.uniprot.org/uniprot/K0AVA1_ECO1C K0AVA1_ECO1C]] DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.[HAMAP-Rule:MF_01321][RuleBase:RU000432] [[http://www.uniprot.org/uniprot/RAPA_ECOLI RAPA_ECOLI]] Transcription regulator that activates transcription by stimulating RNA polymerase (RNAP) recycling in case of stress conditions such as supercoiled DNA or high salt concentrations. Probably acts by releasing the RNAP, when it is trapped or immobilized on tightly supercoiled DNA. Does not activate transcription on linear DNA. Probably not involved in DNA repair (By similarity).<ref>PMID:11751638</ref>
