Introduction
Proteinase K is a subtilisin-like protease with serine as the active center, with a relative molecular weight of about 29.3 kDa. It has a wide range of substrate specificity, and preferentially decomposes the C-terminus adjacent to hydrophobic amino acids, sulfur-containing amino acids, and aromatic amino acids. ester and peptide bonds. It has high activity in the buffer solution for extracting DNA and RNA, and is mainly used for protein digestion during DNA and RNA extraction.
