The two eukaryotic subunits Rpb3 and Rpb11 dimerise to from a platform onto which the other subunits of the RNA polymerase assemble (D/L in archaea). The prokaryotic equivalent of the Rpb3/Rpb11 platform is the alpha-alpha dimer. The dimerisation domain of the alpha subunit/Rpb3 is interrupted by an insert domain (Pfam:PF01000). Some of the alpha subunits also contain iron-sulphur binding domains (Pfam:PF00037). Rpb11 is found as a continuous domain. Members of this family include: alpha subunit from eubacteria, alpha subunits from chloroplasts, Rpb3 subunits from eukaryotes, Rpb11 subunits from eukaryotes, RpoD subunits from archaeal spp, and RpoL subunits from archaeal spp.	Domain

This domain is found in bacteria. This domain is about 360 amino acids in length. This domain is found associated with Pfam:PF00271, Pfam:PF00176. The function of this domain is not known, but structurally it forms an alpha-beta fold in nature with a central beta-sheet flanked by helices and loops, the beta-sheet being mainly antiparallel and flanked by four alpha helices, among which the two longer helices exhibit a coiled-coil arrangement.	Domain
K, L	PF00271	Helicase conserved C-terminal domain (Helicase_C)	Helicase conserved C-terminal domain	The Prosite family is restricted to DEAD/H helicases, whereas this domain family is found in a wide variety of helicases and helicase related proteins. It may be that this is not an autonomously folding unit, but an integral part of the helicase.	Domain

This is one of two Tudor-like domains found in the N-terminal region of RapA proteins. RapA is an abundant RNAP-associated protein of 110-kDa molecular weight with ATPase activity. It forms a stable complex with the RNAP core enzyme, but not with the holoenzyme. The ATPase activity of RapA increases upon its binding to RNAP [1]. The N-terminal region of RapA contains two copies of a Tudor-like domains, both folded as a highly bent antiparallel beta-sheet. This fold is also found in transcription factor NusG , ribosomal protein L24, human SMN (survival of motor neuron) protein, mammalian DNA repair factor 53BP1, putative fission yeast DNA repair factor Crb2 and bacterial transcription-repair coupling factor known as Mfd. The functional roles of the N-terminal region homologs in these proteins suggest that the Tudor-like domains of RapA may interact with both nucleic acids and RNAP [2].	Domain
K, L	PF00176	SNF2-related domain (SNF2-rel_dom)	SNF2-related domain	This domain is found in proteins involved in a variety of processes including transcription regulation (e.g., SNF2, STH1, brahma, MOT1), DNA repair (e.g., ERCC6, RAD16, RAD5), DNA recombination (e.g., RAD54), and chromatin unwinding (e.g., ISWI) as w ...	This domain is found in proteins involved in a variety of processes including transcription regulation (e.g., SNF2, STH1, brahma, MOT1), DNA repair (e.g., ERCC6, RAD16, RAD5), DNA recombination (e.g., RAD54), and chromatin unwinding (e.g., ISWI) as well as a variety of other proteins with little functional information (e.g., lodestar, ETL1)[1,2,3]. SNF2 functions as the ATPase component of the SNF2/SWI multisubunit complex, which utilises energy derived from ATP hydrolysis to disrupt histone-DNA interactions, resulting in the increased accessibility of DNA to transcription factors.

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). Rpb2 is the second largest subunit of the RNA polymerase. This domain forms one of the two distinctive lobes of the Rpb2 structure. This domain is also known as the lobe domain [1]. DNA has been demonstrated to bind to the concave surface of the lobe domain, and plays a role in maintaining the transcription bubble [1]. Many of the bacterial members contain large insertions within this domain, as region known as dispensable region 1 (DRI).	Domain

RNA polymerases catalyse the DNA-dependent polymerisation of RNA. Prokaryotes contain a single RNA polymerase compared with three in eukaryotes (not including mitochondrial or chloroplast polymerases). This domain in prokaryotes spans the gap between domains 4 and 5 of the yeast protein.

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). Rpb2 is the second largest subunit of the RNA polymerase. This domain comprised of the structural domains anchor and clamp [1]. The clamp region (C-terminal) contains a zinc-binding motif [1]. The clamp region is named due to its interaction with the clamp domain found in Rpb1. The domain also contains a region termed "switch 4". The switches within the polymerase are thought to signal different stages of transcription [1].	Domain

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
