Merck, 10103578001, Collagenase A

Collagenase is a protease which cleaves the triple-helical protein called collagen. Clostridium histolyticum produces six types of collagenases namely, α, β, γ, δ, ε and λ. These collagenases are active against connective tissue and show more reactivity towards gelatin than collagen. Collagenase obtained from Clostridium histolyticum has a very strong activity, as it digests collagen from both ends, at temperatures as low as 4-10 °C.
