(2S,4R)-4-Hydroxyproline, or L-hydroxyproline (C5H9O3N), is an amino acid, abbreviated as Hyp or O, e.g., in Protein Data Bank. In 1902, Hermann Emil...

its high hydroxyproline content. The most common motifs in the amino acid sequence of collagen are glycine-proline-X and glycine-X-hydroxyproline, where...

type is proline, although the related non-proteinogenic amino acids hydroxyproline and pipecolic acid have often been included in studies of this class...

Glycine, proline, and hydroxyproline must be in their designated positions with the correct configuration. For example, hydroxyproline in the Y position increases...

In enzymology, a [Skp1-protein]-hydroxyproline N-acetylglucosaminyltransferase (EC 2.4.1.229) is an enzyme that catalyzes the chemical reaction UDP-N-acetylglucosamine...

contains a hydroxyproline at almost every 3rd residue in its amino acid sequence. Collagen consists of both 3‐hydroxyproline and 4‐hydroxyproline residues...

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...

directly and in isolation by standard cellular machinery. For example, hydroxyproline, is synthesised from proline. Another example is selenomethionine)....

proteins (1-5%) are found in most plant cell walls; they are classified as hydroxyproline-rich glycoproteins (HRGP), arabinogalactan proteins (AGP), glycine-rich...

from serine, glycine can also be derived from threonine, choline or hydroxyproline via inter-organ metabolism of the liver and kidneys. Glycine is degraded...
