RpoS mRNA 5'UTR

Index RpoS mRNA 5'UTR

rpoS mRNA encodes for the rpoS stress factor, sigma S (σS or σ38) in Escherichia coli and related bacteria, where DsrA in conjunction with the Sm like RNA binding protein, Hfq promote the translation of this rpoS mRNA. [1]

Acetylation

Acetylation (or in IUPAC nomenclature ethanoylation) describes a reaction that introduces an acetyl functional group into a chemical compound.

Biomolecular structure

Biomolecular structure is the intricate folded, three-dimensional shape that is formed by a molecule of protein, DNA, or RNA, and that is important to its function.

DsrA RNA

DsrA RNA is a non-coding RNA that regulates both transcription, by overcoming transcriptional silencing by the nucleoid-associated H-NS protein, and translation, by promoting efficient translation of the stress sigma factor, RpoS.

Escherichia coli

Escherichia coli (also known as E. coli) is a Gram-negative, facultatively anaerobic, rod-shaped, coliform bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms (endotherms).

Hfq protein

The Hfq protein (also known as HF-I protein) encoded by the hfq gene was discovered in 1968 as an Escherichia coli host factor that was essential for replication of the bacteriophage Qβ.

Messenger RNA

Messenger RNA (mRNA) is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression.

RpoS

The gene rpoS (RNA polymerase, sigma S) encodes the sigma factor sigma-38 (σ38, or RpoS), a 37.8 kD protein in Escherichia coli.

Shine-Dalgarno sequence

The Shine-Dalgarno (SD) Sequence is a ribosomal binding site in bacterial and archaeal messenger RNA, generally located around 8 bases upstream of the start codon AUG.

Site-directed mutagenesis

Site-directed mutagenesis is a molecular biology method that is used to make specific and intentional changes to the DNA sequence of a gene and any gene products.

Stem-loop

Stem-loop intramolecular base pairing is a pattern that can occur in single-stranded DNA or, more commonly, in RNA.

Translation (biology)

In molecular biology and genetics, translation is the process in which ribosomes in the cytoplasm or ER synthesize proteins after the process of transcription of DNA to RNA in the cell's nucleus.

Untranslated region

In molecular genetics, an untranslated region (or UTR) refers to either of two sections, one on each side of a coding sequence on a strand of mRNA.
