[[http://www.uniprot.org/uniprot/VRPI_BPT7 VRPI_BPT7]] Bacterial RNA polymerase inhibitor, which is expressed in the late stage of lytic development, is also essential for continuous synthesis of phage DNA and functions in the packaging of the viral genome into the mature phage particle. [[http://www.uniprot.org/uniprot/C9QUL2_ECOD1 C9QUL2_ECOD1]] 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 (By similarity).[HAMAP-Rule:MF_00366][SAAS:SAAS012293_004_017283] [[http://www.uniprot.org/uniprot/C9QXI7_ECOD1 C9QXI7_ECOD1]] DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates (By similarity).[HAMAP-Rule:MF_00059] [[http://www.uniprot.org/uniprot/C5A0S8_ECOBW C5A0S8_ECOBW]] DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates (By similarity).[SAAS:SAAS012754_004_011999] [[http://www.uniprot.org/uniprot/C9QV90_ECOD1 C9QV90_ECOD1]] DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates (By similarity).[HAMAP-Rule:MF_01321][RuleBase:RU000432] [[http://www.uniprot.org/uniprot/RPOD_ECOLI RPOD_ECOLI]] Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
