What does collagenase mean?
Collagenase is an enzyme that degrades collagen, the fibrous protein that gives strength and structure to skin, bone, tendons, and other connective tissues. By cleaving collagen molecules into smaller fragments, collagenase allows living organisms to remodel tissue during growth, wound healing, and development — but when its activity runs unchecked it can contribute to conditions such as arthritis, tumour invasion, and gum disease. Certain bacteria, notably Clostridium histolyticum, produce powerful collagenases that help them invade host tissue, a property harnessed medically: purified bacterial collagenase is used to clean dead tissue from chronic wounds and, injected directly, to break down the cord of tissue in Dupuytren's contracture. The term belongs mainly to biochemistry, laboratory practice, and clinical medicine, where it names both the natural enzymes (often classified among the matrix metalloproteinases) and commercial preparations used to digest collagen deliberately.
nounAn enzyme that breaks down collagen, the main structural protein of connective tissue, by hydrolysing it into smaller peptide fragments.
- Any enzyme that catalyses the breakdown of collagen, especially those produced by bacteria such as Clostridium histolyticum or naturally occurring matrix metalloproteinases in animals.
- A pharmaceutical preparation of such an enzyme used clinically to debride wounds, treat Dupuytren's contracture (as clostridium collagenase injection), or otherwise digest unwanted collagenous tissue.
"The wound-healing process depends on carefully regulated levels of collagenase to remodel damaged tissue."
"Researchers measured collagenase levels in the synovial fluid of patients with rheumatoid arthritis."
"A topical ointment containing collagenase was applied to the ulcer to help remove dead tissue."
Plural used when referring to multiple distinct enzyme types or preparations.
"Several collagenases have been identified within the matrix metalloproteinase family."
Without collagenase, your body couldn't remodel wounds, and bacteria like Clostridium couldn't use it as a weapon to dissolve through tissue.

Etymology of collagenase
Collagenase is a modern scientific coinage formed from 'collagen' plus the suffix '-ase', which chemists adopted from 'diastase' in the late nineteenth century to name enzymes generally. The root traces back through French collagène to the Greek kolla, meaning glue, reflecting collagen's historical role as the source of animal glue and gelatin. The word thus shares its origin with related terms such as collagenous and, more distantly, with gelatin-derived nomenclature built on the same Greek root.
How collagenase is actually used
Strictly a scientific and medical term; rarely encountered outside biochemistry, cell biology, dermatology, and laboratory contexts. In research papers it is often used generically for any collagen-degrading enzyme, whereas clinical usage may distinguish specific types such as bacterial (clostridial) versus mammalian collagenases.
Easily confused with collagenase
Collagen is the structural protein itself, while collagenase is the enzyme that degrades it.
