[[http://www.uniprot.org/uniprot/RPOA_ECOLI RPOA_ECOLI]] DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. This subunit plays an important role in subunit assembly since its dimerization is the first step in the sequential assembly of subunits to form the holoenzyme.[HAMAP-Rule:MF_00059] [[http://www.uniprot.org/uniprot/NUSG_ECOLI NUSG_ECOLI]] Participates in transcription elongation, termination and antitermination. In the absence of Rho, increases the rate of transcription elongation by the RNA polymerase (RNAP), probably by partially suppressing pausing. In the presence of Rho, modulates most Rho-dependent termination events by interacting with the RNAP to render the complex more susceptible to the termination activity of Rho. May be required to overcome a kinetic limitation of Rho to function at certain terminators. Also involved in ribosomal RNA and phage lambda N-mediated transcriptional antitermination.<ref>PMID:1532577</ref> <ref>PMID:1547498</ref> <ref>PMID:7505669</ref> <ref>PMID:8422985</ref> <ref>PMID:7868616</ref> <ref>PMID:7761393</ref> <ref>PMID:10383769</ref> <ref>PMID:10820031</ref> <ref>PMID:14973028</ref> [[http://www.uniprot.org/uniprot/NUSA_ECOLI NUSA_ECOLI]] Participates in both transcription termination and antitermination. Involved in a variety of cellular and viral termination and antitermination processes, such as Rho-dependent transcriptional termination, intrinsic termination, and phage lambda N-mediated transcriptional antitermination. Also important for coordinating the cellular responses to DNA damage by coupling the processes of nucleotide excision repair and translesion synthesis to transcription.<ref>PMID:6263495</ref> <ref>PMID:6265785</ref> <ref>PMID:6199039</ref> <ref>PMID:2821282</ref> <ref>PMID:7536848</ref> <ref>PMID:9139668</ref> <ref>PMID:11719185</ref> <ref>PMID:20696893</ref> <ref>PMID:21922055</ref> [[http://www.uniprot.org/uniprot/RPOB_ECOLI RPOB_ECOLI]] DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.[HAMAP-Rule:MF_01321] [[http://www.uniprot.org/uniprot/RPOZ_ECOLI RPOZ_ECOLI]] 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] [[http://www.uniprot.org/uniprot/RPOC_ECO57 RPOC_ECO57]] DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. | ||
