WebJul 26, 2024 · The characteristic primary structure of collagen α chains, glycine as every third residue and the presence of hydroxylated proline residues, enables the formation of collagenous triple helix. Proline residues are hydroxylated co- and post-translationally by three isoenzymes forming the group of C-P4Hs and by C-P3Hs. WebThe occurrence of the collagen triple helix illustrates its role in protein function (Fig. 1). In all cases, the triple helix forms a rodlike structure, but this rod can have a kink, as in C1q and MBL, or have flexible interrup-tions, as in type IV collagen. In most cases, the collagen triple helix self-associates to form a higher-order structure.
