Collagenase is an enzyme that breaks down collagen, a key structural protein in connective tissues. In clinical practice, it is significant for its role in wound debridement, particularly in chronic wounds and burns, as it facilitates the removal of necrotic tissue and promotes healing. A notable application is in the treatment of Dupuytren's contracture, where collagenase injections can help release the fibrous tissue, improving hand function and reducing surgical intervention.
