Pancreatic Ribonuclease (RNase I) catalyzes cleavage of the phosphodiester bond between the 5'-ribose of a nucleotide and the phosphate group attached to the 3'-ribose of an adjacent pyrimidine nucleotide forming a 2',3'-cyclic phosphate which may then be hydrolyzed to the corresponding 3'-nucleoside phosphate. Ribonuclease A has a molecular weight of 13,700 daltons. It operates in an optimum PH range of 7.0-7.5.
The high purity Ribonuclease of Enzymeking Biotechnology Co., Ltd.. is purified by re-crystallization, and then by Ion Exchange Chromatography and ultra-filtration.
