-	Bacteriophage T7 encodes an essential inhibitor of the Escherichia coli host RNA polymerase (RNAP), the product of gene 2 (Gp2). We determined a series of X-ray crystal structures of E. coli RNAP holoenzyme with or without Gp2. The results define the structure and location of the RNAP sigma70 subunit domain 1.1 inside the RNAP active site channel, where it must be displaced by the DNA upon formation of the open promoter complex. The structures and associated data, combined with previous results, allow for a complete delineation of the mechanism for Gp2 inhibition of E. coli RNAP. In the primary inhibition mechanism, Gp2 forms a protein-protein interaction with , preventing the normal egress of from the RNAP active site channel. Gp2 thus misappropriates a domain of the RNAP holoenzyme, , to inhibit the function of the enzyme.

		+	[[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. This is the primary sigma factor of this bacterium.
