Galactose-3-O-sulfotransferase 3 is an enzyme that in humans is encoded by the GAL3ST3 gene.This gene encodes a member of the galactose-3-O-sulfotransferase protein family. The product of this gene catalyzes sulfonation by transferring a sulfate group to the 3′ position of galactose in N-acetyllactosamine in both type 2 (Gal-beta-1-4GlcNAc-R) oligosaccharides and core-2-branched O-glycans but not on type 1 or core-1-branched structures.
