This RNase Pancreatic Ribonuclease catalyzes the breakdown of a phosphodiester bond between a nucleotide's 5'-ribose and the phosphate group connected to the 3'-ribose of a neighboring pyrimidine nucleotide, resulting in the formation of a 2',3'-cyclic phosphate that may subsequently be hydrolyzed to the matching 3'-nucleoside. It is an enzyme that aids in the digestion of RNA in vertebrate species and catalyzes the destruction of RNA. The pH range of 7.0 to 7.5 is ideal for this RNase Pancreatic Ribonuclease to function.
