Heparan sulphate (HS) is a highly complex linear polysaccharide found attached to core proteins both on the cell surface and in the extracellular matrix. Newly synthesized HS chains are modified by a family of enzymes, many of which have multiple isoforms with differing substrate preferences. These modifications include the addition of sulphate groups at up to four positions on each disaccharide unit. The pattern of modifications a HS saccharide undergoes alters its structure,...
