Collagenase (non-MMP): Difference between revisions

Latest revision as of 11:41, 5 June 2024

Collagenase (Col) catalyzes the breaking of peptide bonds in collagen. Col cleaves pro-collagen to create collagen. Some collagenases are part of the Matrix metalloproteinase family.

Collagenase G recognises and unravels collagen microfibrils into triple helices and unwind them^[1].
Collagenase H targets collagen III^[2].

Relevance

Col is used for therapy of wounds, Dupuytren's contracture and Peyronie's disease.

Structural highlights

Clostridium histolycum collagenase contains several domains among them: peptidase domain (residues 331-721), polycystic kidney disease domain (PKD residues 792-880), collagen-binding domain (CBD residues 1003-1118). The peptidase domain contains a , a and an .^[3] Water molecules are shown as red spheres. .
