Proteinase K with CAS 39450-01-6
Proteinase K CAS 39450-01-6 is a serine protease belonging to the subtilisin family with efficient enzymatic activity and broad substrate specificity, which preferentially decomposes ester bonds and peptides adjacent to the C-terminus of hydrophobic amino acids, sulfur-containing amino acids, and aromatic amino acids bonds, which are often used to degrade proteins to produce short peptides. Proteinase K has the characteristic of the typical catalytic triad Asp39-His69-Ser224 unique to serine proteases and has two Ca2+ binding sites around the active center to increase its stability and maintain high enzymatic activity under a wider range of conditions.
