Activators: Ca²⁺ is required. Inhibitors: Metal chelating agents such as cysteine, EDTA or o-phenanthroline but not DFP. It is also inhibited by a2-macroglobulin - a large plasma glycoprotein. The human skin enzyme is inhibited by human serum but granulocyte collagenase is not. Human serum contains a2-macroglobulin and a1-antitrypsin that may inhibit certain collagenases.

Thrombin is a protease used to digest fusion proteins prepared from pGEX vectors containing the recognition sequence for thrombin (pGEX-1lT, pGEX-2T, pGEX-2TK, pGEX-4T-1, pGEX-4T-2, and pGEX-4T-3).

Streptokinase catalyzes hydrolysis of amide linkages. Forms a 1:1 complex with plasminogen which is then converted to streptokinase-plasmin. Both streptokinase-plasminogen and streptokinase-plasmin complexes can activate plasminogen. As a result of its interaction with human or rabbit plasminogen, streptokinase undergoes specific fragmentation.

Proteinase K is a highly active stable endopeptidase with a broad spectrum of action was isolated by E. Merk's Darmstadt Biochemical Research Department in 1970 from a culture filtrate of the fungus, Tritirachium album Limber. This fungus is able to grow on Keratin (e.g., wool, horn particles) as the sole source of carbon and nitrogen. The isolated protease was, therefore, given the K designation.
Proteinase K is a stable and highly reactive serine protease. Evidence from crystal and molecular structure studies indicates the enzyme belongs to the subtilisin family with an active-site catalytic triad (Asp39-His69-Ser224). It is stable in a broad range of environments: pH, buffer salts, detergents (SDS), and temperature. In the presence of 0,1 to 0,5% SDS, proteinase K retains activity and will digest a variety of proteins and nucleases in DNA preparations without compromising the integrity of the isolated DNA.

Soluble in distilled water. Soluble in 0,1 M potassium phosphate buffer, pH 6,0 (monobasic potassium phosphate adjusted to pH 6,0 with 1,0 M potassium hydroxide) (10 mg/ml yields a clear, red-brown solution). Solutions of HRP can be kept refrigerated for up to a year while maintaining practically undiminished activity. Optimal pH is 6,0 to 6,5 (activity at pH 7,5 is 84% of the maximum). The enzyme is most stable in the pH range of 5,0 to 9,0 (Lit.).
