Function

COLH_HATHI Clostridial collagenases are among the most efficient degraders of eukaryotic collagen known; saprophytes use collagen as a carbon source while pathogens additionally digest collagen to aid in host colonization. Has both tripeptidylcarboxypeptidase on Gly-X-Y and endopeptidase activities; the endopeptidase cuts within the triple helix region of collagen while tripeptidylcarboxypeptidase successively digests the exposed ends, thus clostridial collagenases can digest large sections of collagen (PubMed:3002446). The full-length protein has collagenase activity, while both the 116 kDa and 98 kDa forms act on gelatin (PubMed:7961400). In vitro digestion of soluble calf skin collagen fibrils requires both ColG and ColH; ColG forms missing the second collagen-binding domain is also synergistic with ColH, although their overall efficiency is decreased (PubMed:18374061, PubMed:22099748). Digestion of collagen requires Ca(2+) and is inhibited by EDTA (PubMed:9452493). The activator domain (residues 119-388) and catalytic subdomain (330-601) open and close around substrate allowing digestion when the protein is closed (PubMed:23703618).[1] [2] [3] [4] [5] [6] [7] [8] [9]
