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.

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).

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.

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].

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).
