Ribonuclease A Protein, Human, Recombinant (His)

RNase A, also known as ribonuclease A and RNASE1, belongs to ribonuclease A superfamily. It is a pancreatic-type of secretory ribonuclease. RNase A is a basic protein and its many positive charges are consistent with its binding to RNA (a poly-anion). More generally, RNase A is unusually polar or, rather, unusually lacking in hydrophobic groups, especially aliphatic ones. As an endonuclease, RNase A cleaves internal phosphodiester RNA bonds on the 3'-side of pyrimidine bases. It prefers poly(C) as a substrate and hydrolyzes 2',3'-cyclic nucleotides, with a pH optimum near 8.0. RNase A is monomeric and more commonly acts to degrade ds-RNA over ss-RNA. Alternative splicing occurs at this locus and four transcript variants encoding the same protein have been identified.

生物活性

Measured by its ability to hydrolyze yeast RNA. One unit of the enzyme causes an increase in absorbance of 1.0 at 260 nm in 15 min when yeast RNA is hydrolyzed at 37°C and pH 7.0. The specific activity is >2.5×106 unit/mg.
