Gelatinase is an enzyme that breaks down gelatin, a protein derived from collagen found in animal tissues. It plays a crucial role in various biological processes, including tissue remodeling and wound healing. Gelatinase is produced by certain bacteria, fungi, and even some human cells, and it helps in the digestion of proteins. In medical and research contexts, gelatinase is often studied for its involvement in diseases, particularly in cancer metastasis and tissue inflammation. By understanding how gelatinase functions, scientists can develop targeted therapies and diagnostic tools to address these health issues more effectively.
