Lysine hydroxylation and cross-linking of collagen

WebProtein hydroxylation is a post-translational modification catalyzed by 2-oxoglutarate-dependent dioxygenases. The hydroxylation modification can take place on various … Lysyl hydroxylases (or procollagen-lysine 5-dioxygenases) are alpha-ketoglutarate-dependent hydroxylases enzymes that catalyze the hydroxylation of lysine to hydroxylysine. Lysyl hydroxylases require iron and vitamin C as cofactors for their oxidation activity. It takes place (as a post-translational modification) following collagen synthesis in the cisternae (lumen) of the rough endoplasmic reticulum (ER). There are three lysyl hydroxylases (LH1-3) encoded in the human … WebThe hydroxylation of specific lysine residues and glycosylation of hydroxylysine residues also occur enzymatically (see below) before the formation of a triple helical procollagen molecule. The procollagen molecules are then transported from the ER to the Golgi stacks, and are secreted to the extracellular space. black and william 2009 assessment
