Galactose-3-O-sulfotransferase 3 (GAL3ST3)

Transfers a sulfate to position 3 of non-reducing beta- galactosyl residues in N-glycans and core2-branched O-glycans. Has high activity towards Gal-beta-1,4-GlcNAc, Gal-beta-1,4(Fuc-alpha- 1,3)GlcNAc and reduced activity towards Gal-beta-1,3(Fuc-alpha- 1,4)GlcNAc.
