WebUnlike heparan sulfate and heparan sulfotransferases, which have been the subject of intense investigations, CS and chondroitin sulfotransferases have not received as much attention until recently. However, several observations suggest important biological roles for specific CS forms, and the chondroitin sulfotransferases involved in their biosynthesis. WebHeparin (HP) and heparan sulfate (HS) are linear, anionically charged polysaccharides well-known for their diverse biological activities. While HP is generally localized in mast cells and in connective tissues, HS is part of the glycocalyx and involved in the attachment of viruses to host cells, constituting the first step of an infection. HP and HS also exhibit …
