heparan sulfate glucosamine 3-O-sulfotransferase M-CSA #999 | 3-O-sulfotransferase (3-OST) is one of the enzymes involved in the biosynthesis of heparan sulfate by catalyzing the transfer of a sulfate group from 3'-phosphoadenosine-5'-phosphosulfate to glucosamine units of heparan sulfate. Heparan sulfates are polysaccharides with variable patterns of sulfation and acetylation that serve as entry receptors for herpes simplex virus type 1 (HSV-1). Therefore, this enzyme might be a target for drugs since its inhibition may lead to the blockage of HSV-1 viral infections. | Defined by 6 residues: LYS:A-28 [auth A-162]GLU:A-50 [auth A-184]HIS:A-52 [auth A-186]ASP:A-55 [auth A-189]LYS:A-81 [auth A-215]LYS:A-234 [auth A-368] | |
