General description

Collagenase II is a metalloprotease that acts as an endoprotease and exhibits a tripeptidyl carboxypeptidase activity. It shows endopeptidic activity with the main cleavage site found in front of the human collagen duplex amino acids glycine-proline. Hydrolysis takes place in the interior of the triple helical domains of collagen. Collagenase II is also known as class II collagenase and consists of three subtypes: δ, ε, and ζ. Collagenase II USP reference standard is provided as delivered and specified by the issuing Pharmacopoeia. All information provided in support of this product, including MSDS and any product information leaflets have been developed and issued under the Authority of the issuing Pharmacopoeia. For further information and support please go to the website of the issuing Pharmacopoeia.

Biochem/physiol Actions

Collagenase is activated by four gram atom calcium per mole enzyme. It is inhibited by ethylene glycol-bis(beta-aminoethyl ether) - N, N, N′,N′-tetraacetic acid, beta-mercaptoethanol, glutathione, thioglycolic acid and 8-hydroxyquinoline.

Unit Definition

One collagen digestion unit (CDU) liberates peptides from collagen from bovine achilles tendon equivalent in ninhydrin color to 1.0 μmole of leucine in 5 hours at pH 7.4 at 37 °C in the presence of calcium ions. One FALGPA hydrolysis unit hydrolyzes 1.0 μmole of furylacryloyl-Leu-Gly-Pro-Ala per min at 25°C. One Neutral Protease unit hydrolyzes casein to produce color equivalent to 1.0 μmole of tyrosine per 5 hr at pH 7.5 at 37°C. One Clostripain Unit hydrolyzes 1.0 μmole of BAEE per min at pH 7.6 at 25°C in the presence of DTT.
