RNA polymerases catalyse the DNA dependent polymerisation of RNA. Prokaryotes contain a single RNA polymerase compared to three in eukaryotes (not including mitochondrial. and chloroplast polymerases). This domain represents the hybrid binding domain and the wall domain [1]. The hybrid binding domain binds the nascent RNA strand / template DNA strand in the Pol II transcription elongation complex. This domain contains the important structural motifs, switch 3 and the flap loop and binds an active site metal ion[1]. This domain is also involved in binding to Rpb1 and Rpb3 [1]. Many of the bacterial members contain large insertions within this domain, as region known as dispensable region 2 (DRII).	Domain

This domain is found at the N terminus in the protein gp35 from Thermus phage P23-45 and similar sequences from tailed bacteriophages. This protein binds the host's DNA-dependent RNA polymerase (RNAP), inhibiting host gene transcription while allowing transcription of phage genes. Structural studies show this core domain of the protein binds to the RNA beta-flap domain. It consists of a central beta sheet and a N-terminal helix [1, 2].	Domain
