Research Abstract

'Flesh-eating bacteria' produce collagenases to hydrolyze collagen fibrils in tissue. These enzymes possess domain(s) to bind to this insoluble substrate (CBD). We identified amino acid residues responsible for the binding. We also showed that CBD binds preferentially to the under-wound region in the collagen molecule, and that the binding is unidirectional. Ca^<2+> binds to the linker region of CBD. We showed that the binding modifies CBD into a more stable and more efficient conformation. Finally, we showed the potential benefits of matrix anchoring of various bioactivity substances using CBD, which are applicable to various therapies in regenerative medicine.
