Proteinase K is a stable serine protease with broad substrate specificity. Proteinase K degrades many proteins in the native state even in the presence

of detergents. Evidence from crystal and molecular structure studies indicates the enzyme belongs to the subtilisin family with an active

site catalytic triad (Asp39-His69-Ser224). The predominant site of cleavage is the peptide bond adjacent to the carboxyl group of aliphatic and

aromatic amino acids with blocked alpha amino groups. Proteinase K is commonly used for its broad specificity.
