WebMar 17, 2024 · Similar to vertebrate collagen, prokaryotic collagen-like proteins contain Gly-X-Y tripeptide repeats, where glycine is required every third residue. The X and Y positions of prokaryotic collagen-like proteins can be occupied by any amino acids, but some residues are preferred (see below). WebEach α(IV) chain in type IV collagen is composed of three distinct domains: a cysteine-rich N-terminal 7S-domain, a central long triple helical collagenous domain with Gly–X–Y repeats (where X and Y represent any amino acids other than glycine, but are often proline and hydroxyproline) interrupted by short NC domain, and a globular C-terminal NC1 … WebThe triple-helical domain includes interrupted G-X-Y repeats. The 7S and NC1 domains are responsible for assembling collagen IV into a three-dimensional structure conditioning both stiffness and flexibility due to numerous Gly-X-Y interruptions .
