Function[HRTD_CROAT] Snake venom zinc metalloproteinase that causes hemorrhage by provoking the degradation of the sub-endothelial matrix proteins (fibronectin, laminin, type IV collagen, nidogen, and gelatins).[1] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe structure of the metalloproteinase and hemorrhagic toxin atrolysin C form d (EC 3.4.24.42), from the venom of the western diamondback rattlesnake Crotalus atrox, has been determined to atomic resolution by x-ray crystallographic methods. This study illuminates the nature of inhibitor binding with natural (< Glu-Asn-Trp, where < Glu is pyroglutamic acid) and synthetic (SCH 47890) ligands. The primary specificity pocket is exceptionally deep; the nature of inhibitor and productive substrate binding is discussed. Insights gained from the study of these complexes facilitate the design of potential drugs to treat diseases where matrix metalloproteinases have been implicated, e.g., arthritis and tumor metastasis. Structural interaction of natural and synthetic inhibitors with the venom metalloproteinase, atrolysin C (form d).,Zhang D, Botos I, Gomis-Ruth FX, Doll R, Blood C, Njoroge FG, Fox JW, Bode W, Meyer EF Proc Natl Acad Sci U S A. 1994 Aug 30;91(18):8447-51.
