Collagenases are enzymes that break down collagen, a protein that provides structure and strength to connective tissues in the body. They play a crucial role in various biological processes, including tissue remodeling, wound healing, and inflammation. By breaking down collagen, these enzymes help facilitate the repair and regeneration of tissues. In medicine, collagenases are used in treatments for conditions like Dupuytren's contracture and chronic wounds. They can also be found in certain products aimed at improving skin health. Understanding collagenases is important for developing therapies that target tissue repair and regeneration effectively.
