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]

Publication Abstract from PubMed

Clostridial collagenases are among the most efficient enzymes to degrade by far the most predominant protein in the biosphere. Here we present crystal structures of the peptidases of three clostridial collagenase isoforms (ColG, ColH and ColT). The comparison of unliganded and liganded structures reveal a quaternary subdomain dynamics. In the unliganded ColH structure this globular dynamics is modulated by an aspartate switch motion that binds to the catalytic zinc. We further identified a calcium binding site in proximity to the catalytic zinc. Both ions are required for full activity, explaining why calcium critically affects the enzymatic activity of clostridial collagenases. Our studies further reveal that loops close to the active site thus serve as characteristic substrate selectivity filter. These elements explain the distinct peptidolytic and collagenolytic activities of these enzymes and provide a rational to engineer collagenases with customized substrate specificity as well as for inhibitor design.
