Web24 apr. 2024 · The up-regulated procollagen-lysine 2-oxoglutarate 5-dioxygenase 2 (PLOD2; lysyl hydroxylase 2) is a membrane-bound homodimeric enzyme, which catalyzes the hydroxylation of lysyl residues in collagen-like proteins . This post-translational modification of lysin is important for the cross-linking and stabilization of collagen filaments. WebIn contrast, lysyl hydroxylation occurs to a much lower extent, especially in type I collagen. From amino acid analysis data, lysyl hydroxylation occurs in about one-third of the Yaa position lysines in the type I collagen triple helical domain. Web1 mai 2016 · Lysyl hydroxylases are endoplasmic reticulum-associated oxidases which require α-ketoglutarate and ascorbate. These cofactors are also required for collagen prolyl hydroxylases.
