Webanchoring function of certain collagen types could contribute to the formation of scaffolds promoting tissue repair or regeneration [2,5,6]. 2. Collagens—the basic structural module The name ‘‘collagen’’ is used as a generic term for proteins forming a characteristic triple helix of three polypeptide chains and all members of the collagen WebCollagens are the most abundant extracellular matrix proteins in vertebrates and have a characteristic triple-helix structure. Hydroxylation of proline residues is critical for helix stability, and diminished prolyl hydroxylase activity causes wide-spread defects in connective tissues. Still, the role of proline hydroxylation in the binding of collagen …
