GAG polysaccharide biosynthetic pathway. Schematic representation of the proteins involved in (i) production of the GAG activate sugar nucleotide precursors (Uge3), (ii) polymerization and transport across the membrane (Gtb3), and (iii) hydrolysis (Sph3/Ega3) and deacetylation (Adg3) of the mature polymer. Abbreviations: Glc, Glucose; GlcNAc, N-acetylglucosamine; Gal, Galactose, GalNAc, N-acetylglucosamine; GalN, Galactosamine. UDP is denoted by a grey pentagon.
