RNA polymerases (RNAPs) carry out transcription in all living organisms. All multisubunit RNAPs are derived from a common ancestor, a fact that becomes apparent from their amino acid sequence, subunit composition, structure, function and molecular mechanisms. Despite the similarity of these complexes, the organisms that depend on them are extremely diverse, ranging from microorganisms to humans. Recent findings about the molecular and functional architecture of RNAPs has given us intriguing… 
Evolutionary Origins of Two-Barrel RNA Polymerases and Site-Specific Transcription Initiation.
TLDR
This review focuses on recent insights into the evolution of the transcription apparatus with regard to the surprisingly pervasive double-Ψ β-barrel active-site configuration among different nucleic acid polymerase families.
Biogenesis of multisubunit RNA polymerases.
TLDR
This review integrates the available data into a model of Pol II biogenesis that provides a framework for future analysis of the biogenesis of all RNA polymerases.
Recent advances in the understanding of archaeal transcription.
TLDR
This review covers recent discoveries about the mechanisms of archaeal transcription obtained by a combination of in vivo and in vitro approaches, from the molecular to the global level.
The cutting edge of archaeal transcription
TLDR
This review focuses on recent progress in understanding of the structure, function and molecular mechanisms of known and less characterized factors including Elf1 (Elongation factor 1), NusA (N-utilization substance A), TFS4, RIP and Eta, and their evolution and phylogenetic distribution across the expanding tree of Archaea.
Structure and Function of RNA Polymerases and the Transcription Machineries.
TLDR
The three-dimensional organisation of RNAPs from the bacterial, archaeal and eukaryotic domains of life is discussed, highlighting the conserved nature, but also the domain-specific features of the transcriptional apparatus.
Multisubunit RNA polymerases IV and V: purveyors of non-coding RNA for plant gene silencing
TLDR
Plants have evolved two additional multisubunit RNA polymerases,RNA polymerases IV and V, which orchestrate non-coding RNA-mediated gene silencing processes affecting development, transposon taming, antiviral defence and allelic crosstalk, and provides the unique opportunity to study the functional diversification of a eukaryotic RNA polymerase family.
Structural biology: A transcriptional specialist resolved
TLDR
The cryo-electron microscopy structures of budding yeast Pol III are determined and an atomic-level model of the complete 17-subunit complex is built, in both unbound and elongating conformations, which allow a detailed comparison with the Pol I and Pol II enzymes and explain the adaptation of this polymerase towards its specific targets.
Eukaryotic RNA Polymerases: The Many Ways to Transcribe a Gene
TLDR
It is proposed that the diversity and instability of messenger RNAs, transcribed by RNA polymerase II, have conditioned the appearance of regulatory mechanisms based on different gene promoter strength and mRNA stability for the regulation of ribosomal RNA levels.
Biogenesis of RNA Polymerases in Yeast
TLDR
This study reviews the latest studies governing the mechanisms and proteins described as being involved in the biogenesis of RNA polymerases in yeast by characterizing some elements involved inThe assembly of these multisubunit complexes.

TLDR
The archaeal RNAP is closely related to eukaryotic RNAPII in terms of subunit composition and architecture, promoter elements and basal transcription factors required for the initiation and elongation phase of transcription.
Molecular evolution of multisubunit RNA polymerases: structural analysis.
TLDR
The alignments were used to delineate sequence regions shared among all classes of multisubunit RNAPs, defining common, fundamental RNAP features as well as identifying highly conserved positions.

TLDR
This review focuses on the multiple functions of the most prominent feature that differentiates these enzymes from the bacterial RNAP--a stalk-like protrusion, which consists of the heterodimeric F/E subcomplex.
Evolution of Complex RNA Polymerases: The Complete Archaeal RNA Polymerase Structure
TLDR
The structure of the 13-subunit DNA-directed RNAP from Sulfolobus shibatae is determined and subunit Rpo13, an RNAP component in the order Solfolobales, which contains a helix-turn-helix motif that interacts with the RpoH/Rpb5 and RpoA′/RPB1 subunits suggest a role in the formation of the transcription bubble.
Hold On! RNA polymerase interactions with the nascent RNA modulate transcription elongation and termination
TLDR
Spt4/5 is the only known RNAP-associated transcription factor that is conserved in all three domains of life, and it stimulates elongation similar to RNAP subunits F/E, and enhances processivity in a fashion that is independent of the nontemplate DNA strand, by interacting with the RNAP clamp.
Structure of eukaryotic RNA polymerases.
TLDR
A catalog of available structural information for Pol I, Pol II, and Pol III is provided, which showed that the active center region and core enzymes are similar to Pol II and that strong structural differences on the surfaces account for gene class-specific functions.
Tethering of the Large Subunits of Escherichia coli RNA Polymerase*

It is shown that in Escherichia colithe two genes can be fused and that the resulting 2751-amino acid β::β′ fusion polypeptide assembles into functional RNA polymerase in vivo and in vitro.

TLDR
The highly conserved ‘funnel’ and ‘switch 2’ components of the active site region are shared by all putative DNA-dependent RNA polymerases and may determine their capacity to transcribe double-stranded DNA templates.

The first crystal structure of the archaeal RNAP is reported from Sulfolobus solfataricus at 3.4 Å resolution, completing the suite of multi-subunit RNAP structures from all three domains of life and providing the first experimental evidence of any RNAP possessing an iron–sulphur (Fe–S) cluster, which may play a structural role in a key subunit of RNAP assembly.
