WebHydroxyproline is a non-essential amino acid found in collagen and few other extracellular animal proteins. It's two isomeric forms trans-4-hydroxy-L-proline and trans-3-hydroxy-L-proline play a crucial role in collagen synthesis and thermodynamic stability of the triple-helical conformation of collagen and associated tissues. WebProline is converted to hydroxyproline by hydroxylation. Proline betaine is seen in members of Plumbaginaceae, Capparidaceae, Rutaceae, Labiatae, Compositae, and Leguminosae (Wyn Jones and Storey, 1981; Hanson et al., 1994).It has been pointed out that proline betaine catabolism contributes to rhizobial colonization of seedling roots (Phillips et al., …
