Summary: 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 hydroxyl at C-3 of nonreducing beta-galactosyl residues, and it can act on both type 1 and type 2 (Galbeta 1-3/1-4GlcNAc-R) oligosaccharides with similar efficiencies, and on core 1 glycans.

The sulfate content of STF series samples was calculated based on the weight loss from 500 to 900 °C. The weight loss corresponded to the SO 3 content. The sulfate content, i.e. SO 4 2− content, would be 1.2 times the weight loss.
