Proteinase K is a highly active serine protease. Its enzyme activity is stable in the presence of calcium salts, and increases when a protein denaturant such as SDS or urea is also present. Proteinase K is compatible with a wide range of substrates. It preferentially degrades estel and peptide bands located next to a C-terminal hydrophobic, sulfuric, or aromatic amino acid.
