Collagen from the skin of wild type and prolyl 4-hydroxylase mutant mice was extracted and proline hydroxylation of the collagen-derived peptides were analyzed by LC-MS/MS.
Type I collagen is the main structural protein in mammals and other vertebrate life forms. During the biosynthesis of collagens, prolyl-3-hydroxylase 1 (P3H1) catalyzes 3-hydroxylation of proline residues and acts as a chaperone. Deficiency of P3H1 causes Osteogenesis Imperfecta (OI), a hereditary d...
