Opis ogólny

RNase A, Ribonuclease A, is an endoribonuclease that cleaves the phosphodiester bonds of single strand RNA after pyrimidine nucleotides. It attacks at the 3′ phosphate end (For example pG-pG-pC-pA-pG will be cleaved to give pG-pG-pCp and A-pG). The highest activity is exhibited with single stranded RNA. RNase A is a single chain polypeptide containing 4 disulfide bridges. In contrast to RNase B, it is not a glycoprotein. Ribonucleases do not hydrolyze DNA, because the DNA lacks 2′-OH groups essential for the formation of cyclic intermediates. RNase A can also hydrolyze RNA from protein samples. RNase A can be inhibited by alkylation of His12 and His119 and activated by potassium and sodium salts. RNAse is inhibited in the presence of heavy metal ions. RNase is also inhibited competitively by DNA.

Zastosowanie

  • RNase A is used to remove RNA from DNA plasmid and genomic DNA preparations and protein samples.
  • RNase A is also used in RNA sequence analysis and protection assays.
  • RNase A has been used as a tool for computer-aided drug design.
  • RNase A supports the analysis of RNA sequences.
  • RNase A hydrolyze RNA contained in protein samples.
  • Purification of DNA is supported by RNase A.

Epigenetic clocks for mice were generated based on deep-sequencing analysis of the methylome. Here, we demonstrate that site-specific analysis of DNA methylation levels by pyrosequencing at only three CG dinucleotides (CpGs) in the genes Prima1, Hsf4, and Kcns1 facilitates precise

The main risk of emergence of prion diseases in humans is associated with a cross-species transmission of prions of zoonotic origin. Prion transmission between species is regulated by a species barrier. Successful cross-species transmission is often accompanied by strain adaptation
