Description

This family includes a variety of sulfotransferase enzymes. Chondroitin 6-sulfotransferase catalyses the transfer of sulfate to position 6 of the N-acetylgalactosamine residue of chondroitin. This family also includes Heparan sulfate 2-O-sulfotransferase (HS2ST) and Heparan sulfate 6-sulfotransferase (HS6ST). Heparan sulfate (HS) is a co-receptor for a number of growth factors, morphogens, and adhesion proteins. HS biosynthetic modifications may determine the strength and outcome of HS-ligand interactions. Mice that lack HS2ST undergo developmental failure only after midgestation,the most dramatic effect being the complete failure of kidney development

. Heparan sulphate 6- O -sulfotransferase (HS6ST) catalyses the transfer of sulphate from adenosine 3'-phosphate, 5'-phosphosulphate to the 6th position of the N -sulphoglucosamine residue in heparan sulphate
