Collagenases are proteinases that hydrolyze collagen under physiological conditions. Collagenase clostridium histolyticum is comprised of a mixture of Class I (AUX-I) and Class II (AUX-II) clostridial collagenases in a defined mass ratio. Both collagenases effectively cleave interstitial collagen but at different sites on the molecule; additionally, they prefer different conformations (triple helical versus denatured or cleaved). |
