Dictionary » R » Ribonuclease


A transferase that catalyzes the hydrolysis of ribonucleic acid.An enzyme that catalyses the depolymerization of RNA.ribonuclease

(Science: Biochemistry, Enzyme, Molecular biology) Widely distributed type of enzyme that cleaves rNA. May act as endonucleases or exonucleases depending upon the type of enzyme. Generally recognise target by tertiary structure rather than sequence.

Ribonuclease E is involved in the formation of 5S ribosomal RNA from pre rRNA.

Ribonuclease F is stimulated by interferons and cleaves viral and host rNA and thus inhibits protein synthesis.

Ribonuclease H specifically cleaves an rNA base paired to a complementary DNA strand.

Ribonuclease P is an endonuclease that generate t rNA from their precursor transcripts.

Ribonuclease T is an endonuclease that removes the terminal aMP from the 3' cCA end of a nonaminoacylated tRNA. Ribonuclease T1 cleaves rNA specifically at guanosine residues. Ribonuclease TIII cleaves double stranded regions of RNA molecules.

Acronym: RNase

Why is bovine pancreas used so much?

... pancreas. Today I read about Anfinsens classic experiment [http://en.wikipedia.org/wiki/Anfinsen%27s_dogma], and apparently they took the enzyme (Ribonuclease A) from bovine pancreas.. I have heard of bovine pancreas being used in a lot of other contexts too. Of all cells from all tissues in and ...

Tissue RNA Extraction Kit

RNA extraction is the purification of RNA from biological samples. This procedure is complicated by the ubiquitous presence of ribonuclease enzymes in cells and tissues, which can rapidly degrade RNA. The GenQuikâ„¢ Tissue RNA Extraction Kit is ideal for rapid and convenient purification ...

Re: Gene cloning question

Hi RNAse is nothing but Ribonuclease which actually cleaves a phosphodiester bond between any two ribonucleotides and also degrades RNA into smaller components which is mostly helpful in prokaryotic processes and play a important role ...
