Web12 Apr 2024 · a 2D projection of the staggered arrangement of collagen triple helices, each 300 nm. This results in the typical overlap and gap regions of collagen, including the 3D braiding of triple helices. WebIn collagen, glycine is required at every third position, because the assembly of the triple helix puts this residue at the interior (axis) of the helix, where there is no space for a larger side group than glycine’s single hydrogen atom. For the same reason, the rings of the Pro and Hyp must point outward.
Metal-assisted Assembly and Stabilization of Collagen-like Triple Helices
WebNearly 30% of human proteins have tandem repeating sequences. Structural understanding of the terminal repeats is well-established for many repeat proteins with the common α-helix and β-sheet foldings. By contrast, the sequence-structure interplay of the terminal repeats of the collagen triple-helix remains to be fully explored.

Web11 Apr 2024 · We have recently used this knowledge for the design of pH-responsive collagen triple helices that bear (4S)-aminoproline (Amp) residues (Figure 2). 5, 15 We showed that changes in pH affect not only the protonation state of the amino group but also trigger a flip of the ring pucker and the formation or release of a transannular H-bond … Web20 May 2024 · Collagen Domains and Macromolecular Assembly. The unifying feature of all collagens is the triple-helical collagenous domain, which is composed of three so-called α-chains consisting of amino acid repeats of (Gly-X-Y) n.The smallest amino acid glycine (Gly) can face the interior part of the triple helix while still allowing for a close association of … WebCollagen triple helices fold slowly and inefficiently, often requiring adjacent globular domains to assist this process.
