Uncovering the effect of RNA polymerase steric interactions on gene expression noise: analytical distributions of nascent and mature RNA numbers [PDF]
arXiv, 2023 The telegraph model is the standard model of stochastic gene expression, which can be solved exactly to obtain the distribution of mature RNA numbers per cell. A modification of this model also leads to an analytical distribution of the nascent RNA numbers. These solutions are routinely used for the analysis of single-cell data, including the inference

Biomolecular Concepts, 2016 The bacterial RNA polymerase (RNAP) holoenzyme is a multisubunit core enzyme associated with a σ factor that is required for promoter-specific transcription initiation. Besides a primary σ responsible for most of the gene expression during active growth,

In vitro Assessment of RNA Polymerase I Activity
Bio-Protocol, 2017 In eukaryotic cells transcriptional processes are carried out by three different RNA polymerases: RNA polymerase I which specifically transcribes ribosomal RNA (rRNA), RNA polymerase II which transcribes protein-coding genes to yield messenger RNAs ...

Reticulocyte RNA-Dependent RNA Polymerase [PDF]
Proceedings of the National Academy of Sciences, 1973 A cytoplasmic, microsomal bound RNA-dependent RNA polymerase has been purified 2500-fold from rabbit reticulocyte lysates. The synthesis of RNA with the purified enzyme is absolutely dependent on the addition of an RNA template. The best template is hemoglobin messenger RNA, while bacteriophage RNA and poly(A,G) are less active, and DNA is completely ...

Taurine promotes glucagon‐like peptide‐1 secretion in enteroendocrine L cells
FEBS Letters, EarlyView.Taurine, a sulfur‐containing amino acid, is likely taken up by enteroendocrine L cells via the taurine transporter. This process increases the levels of cytosolic ATP. The increase in intracellular Ca2+ concentrations and glucagon‐like peptide‐1 secretion through membrane depolarization is caused by the closure of ATP‐sensitive potassium channels ...

eLife, 2015 Errors during transcription may play an important role in determining cellular phenotypes: the RNA polymerase error rate is >4 orders of magnitude higher than that of DNA polymerase and errors are amplified >1000-fold due to translation.

Oligomerization of the E. coli core RNA polymerase: formation of (α2ββ'ω)2-DNA complexes and regulation of the oligomerization by auxiliary subunits. [PDF]
PLoS ONE, 2011 In this work, using multiple, dissimilar physico-chemical techniques, we demonstrate that the Escherichia coli RNA polymerase core enzyme obtained through a classic purification procedure forms stable (α(2)ββ'ω)(2) complexes in the presence or absence of

Electrostatic map of T7 DNA. Comparative analysis of functional and electrostatic properties of T7 RNA polymerase specific promoters [PDF]
, 2013 The entire T7 bacteriophage genome contains 39937 base pairs (Database NCBI RefSeq N1001604). Here, electrostatic potential distribution around double helical T7 DNA was calculated by Coulomb method using the computer program of Sorokin A.A. Electrostatic profiles of 17 promoters recognized by T7 phage specific RNA polymerase were analyzed.
