glycosaminoglycan-protein linkage region biosynthetic process
glycosaminoglycan-protein linkage region biosynthetic process
The formation of a tetrasaccharide linker sequence (xylose-galactose-galactose-glucuronate) on specific serine residues of a core protein, on to which dermatan sulfate, chondroitin sulfate, heparan sulfate or heparin glycosaminoglycans may be assembled to synthesise the corresponding proteoglycan.
