General Information
Term heparan sulfate proteoglycan biosynthetic process ID (Ontology) GO:0015012 (Gene Ontology)
Definition The chemical reactions and pathways resulting in the formation of heparan sulfate proteoglycans, which consist of a core protein linked to a heparan sulfate glycosaminoglycan. The heparan sulfate chain is composed of the repeating disaccharide unit beta-(1,4)-N-acetyl-D-glucosamine-alpha-(1,4)-hexuronic acid, the former being either sulfated or deacetylated on its amino group as well as sulfated on one of its hydroxyl groups, and the latter being e a mixture of sulfated and nonsulfated D-glucuronic and L-iduronic acids. Heparan sulfate chains are covalently linked to serine/threonine residues (O-linked) of the core protein via a tetrasaccharide linker sequence (xylose-galactose-galactose-glucuronate).[ PubMed:27241222 ]
Also Known As "heparan sulfate proteoglycan anabolism" ; "heparan sulfate proteoglycan biosynthesis" ; "heparan sulfate proteoglycan formation" (for all, see Synonyms field below)
