==Function==

[[http://www.uniprot.org/uniprot/H0QDQ9_ECOLI H0QDQ9_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 (By similarity).[HAMAP-Rule:MF_00366][SAAS:SAAS003716_004_017283] [[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/RPOC_ECOLI RPOC_ECOLI]] DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.[HAMAP-Rule:MF_01322] [[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/RPOD_ECOLI RPOD_ECOLI]] Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This is the primary sigma factor of this bacterium.
