PRODUCT DESCRIPTION

SPECIFICATIONS
SKU: 02101076-CF
Base Catalog Number: 101076
Alternate Names: Pancreatic Ribonuclease; RNase A; Ribonuclease I; Ribonucleate 3' pyrimidinooligonucleotidohydrolase
Biochemical Physiological Actions : Ribonuclease A is an endoribonuclease that cleaves single stranded RNA after pyrimidine nucleotides. It attacks at the 3’ phosphate end. Ribonucleases do not hydrolyze DNA, because the DNA lacks 2'-OH groups essential for the formation of cyclic intermediates. RNase 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.

Specificity : The enzyme is specific for pyrimidine nucleoside linkages; i.e.; those cleaving cyclic 2';3'-pyrimidine nucleotide residues either singly or at the termination of purine nucleotide chains.
Unit Definition : That amount of enzyme causing the hydrolysis of RNA at a rate such that k (velocity constant) equals unity at 25 °C and pH 5.0.
