SYSTEMATIC NAME
IUBMB Comments
nucleoside-triphosphate:RNA nucleotidyltransferase (DNA-directed)
Catalyses DNA-template-directed extension of the 3'- end of an RNA strand by one nucleotide at a time. Can initiate a chain de novo. In eukaryotes, three forms of the enzyme have been distinguished on the basis of sensitivity to alpha-amanitin, and the type of RNA synthesized. See also EC 2.7.7.19 (polynucleotide adenylyltransferase) and EC 2.7.7.48 (RNA-directed RNA polymerase).

COMMENTARY
LITERATURE
evolution
-
human mitochondrial RNA polymerase is distantly related to the bacteriophage T7 class of single-subunit RNAPs with a probably similar mechanisms for nucleotide binding, substrate selection and catalysis/nucleotidyl transfer. The C-terminal domain contains the regions of highest similarity to the phage RNAPs. Early in the evolution of eukaryotes there has been a switch from a multi-subunit prokaryotic polymerase to a single-subunit, phage-derived polymerase, encoded in the nuclear genome and imported into the mitochondria, to serve as the transcriptase of the mitochondrial genome. The POLRMT CTD is characteristic of the Pol I family of nucleic acid polymerases, typically described as resembling the shape of a cupped right hand, containing the fingers, palm and thumb subdomains. The palm subdomain contains several key structural motifs that are highly conserved among the different classes of nucleic acid polymerases
evolution
-
Rpo41 utilizes a promoter recognition loop to bind and recognize its promoter, analogous to the use of the specificity loop by T7 RNAP for this purpose
malfunction
-
reverse translocation, i.e. backtracking, by a distance of one or more nucleotides disrupts the configuration of the catalytic center, leading to a temporary, spontaneously resolved, halt of the RNAP, called pausing, or to a transition into an irreversible arrested state. The latter can be restored to functionality by the endonucleolytic cleavage of the RNA or by pushing the backtracked complex from behind. Non-backtracked paused complexes are also described for bacterial RNAPs, where addition of the incoming NTP is hindered owing to isomerization of the active site into an inactive conformation
malfunction
-
DNA topoisomerase I inhibition by camptothecin induces escape of RNA polymerase II from promoter-proximal pause site, antisense transcription and histone acetylation at the human HIF-1alpha gene locus
malfunction
-

malfunction
-
R428A RNAP is instable
malfunction
-
at lower concentrations, pyrimidine nucleoside analogs have the potential to more easily inhibit mitochondrial transcription and mediate toxicity, given the ability to be readily phosphorylated and serve as efficient substrates for the enzyme
malfunction
-
replication intermediates associated with an unusually prolonged delay in the initiation of second strand DNA synthesis are enhanced by combined shRNA and dsRNA POLRMT gene silencing
physiological function
-
Pol II is the eukaryotic enzyme that is responsible for transcribing all protein-coding genes into mRNA. The mRNA-transcription cycle can be divided into three stages: initiation, elongation and termination. During elongation, Pol II moves along a DNA template and synthesizes a complementary RNA chain in a processive manner

the enzyme can be involved in both replication and integration processes of these plasmid in the mitochondrial genome
physiological function
-
RNA polymerase II has a regulatory function on nucleoside triphosphate synthesis, mutations of RNA polymerase II activate key genes of the nucleoside triphosphate biosynthetic pathways, overview
physiological function
-
the enzyme is required for expression of 13 subunits of the respiratory chain complexes involved in oxidative phosphorylation and two rRNAs and 22 tRNAs, required for mitochondrial translation. In addition to its role in transcription, in the mitochondria, POLRMT serves as the primase for mitochondrial DNA replication. Mechanisms and species specificity for promoter recognition, overview. Complex formation between the enzyme and the other transcription factors at the promoter, the structural elements of the enzyme are repositioned in such a way as to allow for specific promoter recognition, open complex formation and transcription initiation
physiological function
-
the enzyme is required for expression of 13 subunits of the respiratory chain complexes involved in oxidative phosphorylation and rRNAs and tRNAs, required for mitochondrial translation. Rpo41 can initiate transcription from negatively supercoiled templates and pre-melted promoter substrates in the absence of the yeast mitochondrial transcription factor, Mtf1. Mechanisms and species specificity for promoter recognition, overview
physiological function
-
mitochondrial DNA is replicated by a unique enzymatic machinery involving the POLRMT-mediated initiation of primer synthesis from a poly-dT stretch in the single-stranded loop region of the light-strand origin of DNA replication, when the single-stranded origin of DNA replication is exposed and adopts a stem-loop structure. The poly-dT repeat region of origin of DNA replication is an essential element for primer synthesis. POLRMT can function as an origin-specific primase in mammalian mitochondria, overview
physiological function
-
the enzyme activates genes for high affinity nutrient scavenging and motility
physiological function
-
increased Pol III transcription accompanies or causes cell transformation. RPC32beta subunit-containing isozyme Pol IIIbeta is ubiquitously expressed and essential for growth of human cells. RPC32alpha subunit-containing isozyme Pol IIIalpha is dispensable for cell survival, with expression being restricted to undifferentiated ES cells and to tumor cells. Dramatic changes in 5S RNA, U6 RNA, and 7SKRNA expression are specifically caused by ectopic expression of RPC32alpha and not due to a general deregulation of transcription
physiological function
-
RNA polymerase binds to the promoter regions of the gdh, rrnC, and rrnE genes encoding glutamate dehydrogenase and rRNA and activates their transcription
malfunction
-
suppression of subunit RPC32alpha expression by siRNAs impedes anchorage-independent growth of HeLa cells, whereas ectopic expression of RPC32alpha in IMR90 fibroblasts enhances cell transformation and dramatically changes the expression of several tumor-related mRNAs and that of a subset of Pol III RNAs

RNAP is an exceptionally complex enzyme that can be thought of as the engine of gene expression, synthesis of RNA transcripts of many thousands of nucleotides without dissociation. Energy, in the form of nucleoside triphosphates, fuels the synthesis of an RNA polymer complementary to specific regions of the DNA template. Like all macromolecular synthesis, RNA synthesis can be divided into three general phases: initiation, elongation, and termination. Importantly, each of these phases can be a target of regulation. Promoter recognition, binding at the extended promoter recognition region, and transcript initiation, RNAP prefers to initiate transcription within a narrow window located between 6 and 9 bp downstream of the -10 element, promoter clearance and elongation, termination and recycling, mechanisms and regulation , overview. The process of start site selection can be governed by the availability of either the +1 or the +2 NTP, depending on the promoter

multi-subunit DNA-dependent RNA polymerases synthesize RNA molecules thousands of nucleotides long. The reiterative reaction of nucleotide condensation occurs at rates of tens of nucleotides per second, invariably linked to the translocation of the enzyme along the DNA template, or threading of the DNA and the nascent RNA molecule through the enzyme. Reiteration of the nucleotide addition/translocation cycle without dissociation from the DNA and RNA requires both isomorphic and metamorphic conformational flexibility of a magnitude substantial enough to accommodate the requisite molecular motions

the enzyme also shows RNA-dependent RNA polymerase activity, EC 2.7.7.48, but slower and less processive than the DNA-dependent activity. During active transcription, Pol II must overcome intrinsic DNA-arrest sites, which are generally rich in A-T base pairs and pose a natural obstacle to transcription. At such sites, Pol II moves backwards along DNA and RNA, resulting in extrusion of the RNA 3' end through the polymerase pore beneath the active site and transcriptional arrest. The RNA cleavage stimulatory factor TFIIS can rescue an arrested polymerase by creating a new RNA 3' end at the active site from which transcription can resume, mechanism, overview

RNAP is an exceptionally complex enzyme that can be thought of as the engine of gene expression, synthesis of RNA transcripts of many thousands of nucleotides without dissociation. Energy, in the form of nucleoside triphosphates, fuels the synthesis of an RNA polymer complementary to specific regions of the DNA template. Like all macromolecular synthesis, RNA synthesis can be divided into three general phases: initiation, elongation, and termination. Importantly, each of these phases can be a target of regulation. Promoter recognition, binding at the extended promoter recognition region, and transcript initiation, RNAP prefers to initiate transcription within a narrow window located between 6 and 9 bp downstream of the -10 element, promoter clearance and elongation, termination and recycling, mechanisms and regulation , overview. The process of start site selection can be governed by the availability of either the +1 or the +2 NTP, depending on the promoter

multi-subunit DNA-dependent RNA polymerases synthesize RNA molecules thousands of nucleotides long. The reiterative reaction of nucleotide condensation occurs at rates of tens of nucleotides per second, invariably linked to the translocation of the enzyme along the DNA template, or threading of the DNA and the nascent RNA molecule through the enzyme. Reiteration of the nucleotide addition/translocation cycle without dissociation from the DNA and RNA requires both isomorphic and metamorphic conformational flexibility of a magnitude substantial enough to accommodate the requisite molecular motions

And UBF has additional roles in regulation of Pol I promoter escape and transcription elongation
-
glutamate
-
glutamate remodels the sigma38 transcription complex for activation. Accumulation of the simple signaling molecule glutamate can reprogram RNA polymerase in vitro without the need for specific protein receptors. During osmotic activation, glutamate appears to act as a Hofmeister series osmolyte to facilitate promoter escape. Escape is accompanied by a remodeling of the key interaction between the sigma38 stress protein and the beta-flap of the bacterial core RNA polymerase. This activation event contrasts with the established mechanism of inhibition in which glutamate, by virtue of its electrostatic properties, helps to inhibit binding to ribosomal promoters after osmotic shock
additional information
-
Pol III initiates and reinitiates transcription in the absence or presence of transcription factors, during the first transcription cycle transcription factors IIIB and IIIC mainly contribute to the selectivity and not to the rate of Pol III association to the template, while their stable association with the promoter in subsequent cycles strongly contributes to the high rate of transcription reinitiation by Pol III

assay for RNA polymerase activity that uses the dye RiboGreen to detect transcripts by fluorescence and is thus free of the expense, short shelf life, and high handling costs of radioisotopes. The method is relatively quick and can be performed entirely in microplate formate, allowing for the processing of dozens to hundreds of samples in parallel
