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.
