2. Hydroxyproline - Wikipedia

   en.wikipedia.org/wiki/Hydroxyproline

   Hydroxyproline and proline play key roles for collagen stability. [4] They permit the sharp twisting of the collagen helix. [ 5 ] In the canonical collagen Xaa-Yaa-Gly triad (where Xaa and Yaa are any amino acid), a proline occupying the Yaa position is hydroxylated to give a Xaa-Hyp-Gly sequence.

3. Procollagen-proline dioxygenase - Wikipedia

   en.wikipedia.org/wiki/Procollagen-proline_di...

   Procollagen-proline dioxygenase catalyzes the following reaction: L-proline + alpha-ketoglutaric acid + O 2 → (2S, 4R)-4-hydroxyproline + succinate + CO 2. The mechanism for the reaction is similar to that of other dioxygenases, and occurs in two distinct stages: [3] In the first, a highly reactive Fe(IV)=O species is produced.

   The systematic name of this enzyme class is UDP-N-acetyl-D-glucosamine:[Skp1-protein]-hydroxyproline N-acetyl-D-glucosaminyl-transferase. Other names in common use include Skp1-HyPro GlcNAc-transferase , UDP-N-acetylglucosamine (GlcNAc):hydroxyproline polypeptide , GlcNAc-transferase , UDP-GlcNAc:Skp1-hydroxyproline GlcNAc-transferase , and UDP ...

5. 4-hydroxyproline epimerase - Wikipedia

   en.wikipedia.org/wiki/4-hydroxyproline_epimerase

   In enzymology, a 4-hydroxyproline epimerase (EC 5.1.1.8) is an enzyme that catalyzes the chemical reaction trans -4-hydroxy-L-proline ⇌ {\displaystyle \rightleftharpoons } cis -4-hydroxy-D-proline Hence, this enzyme has one substrate , trans-4-hydroxy-L-proline , and one product , cis-4-hydroxy-D-proline .

6. Immunoassay - Wikipedia

   The amount of labelled antibody on the site is then measured. It will be directly proportional to the concentration of the analyte because the labelled antibody will not bind if the analyte is not present in the unknown sample. This type of immunoassay is also known as a sandwich assay as the analyte is "sandwiched" between two antibodies.

9. Collagen helix - Wikipedia

   en.wikipedia.org/wiki/Collagen_helix

   In 1954, Ramachandran & Kartha (13, 14) advanced a structure for the collagen triple helix on the basis of fiber diffraction data. It consists of a triple helix made of the repetitious amino acid sequence glycine-X-Y, where X and Y are frequently proline or hydroxyproline. [2] [3] Collagen folded into a triple helix is known as tropocollagen.
