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]<ref>PMID:19926651</ref> [[http://www.uniprot.org/uniprot/RPOA_MYCS2 RPOA_MYCS2]] DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.[HAMAP-Rule:MF_00059]<ref>PMID:19926651</ref> [[http://www.uniprot.org/uniprot/RPOC_MYCS2 RPOC_MYCS2]] DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.[HAMAP-Rule:MF_01322]<ref>PMID:19926651</ref> [[http://www.uniprot.org/uniprot/RPOB_MYCS2 RPOB_MYCS2]] DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. This subunit often mutates to generate rifampicin (Rif) resistance. Interaction with RbpA partially restores Rif-inhibited transcription; once the subunit is Rif-resistant however RbpA no longer stimulates transcription.[HAMAP-Rule:MF_01321]<ref>PMID:19926651</ref> [[http://www.uniprot.org/uniprot/A0QW02_MYCS2 A0QW02_MYCS2]] Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the primary sigma factor during exponential growth.[SAAS:SAAS00535554] | ||
