The cDNA and gene encoding human N-acetylglucosamine-6-O-sulfotransferase (Gn6ST) have been cloned. Comparative analysis of this cDNA with the mouse Gn6ST sequence indicates 96% amino acid identity between the two sequences. The expression of a soluble recombinant form of the protein in COS-1 cells produced an active sulfotransferase, which transferred sulfate to the terminal GlcNAc in GlcNAcbeta1-O-CH(3), GlcNAcbeta1-3Galbeta1-O-CH(3) and GlcNAcbeta1-3Galbeta1-4GlcNAcbeta1-3Galbeta1-4Gl cNAc but not in GlcNAcalpha1-4GlcAbeta1-3Galbeta1-3Galbeta1-4 Xylbeta1-O-Ser. In addition, neither Galbeta1-4GlcNAcbeta1-O-naphthalenemethanol nor GalNAcbeta1-4GlcAbeta1-3Galbeta1-3Galbeta1-4X ylbeta1-O-Ser were utilized as acceptors. These findings indicate that a terminal beta-linked GlcNAc residue is necessary for acceptor substrates of Gn6ST. The human Gn6ST gene spans about 7 kb, consists of two exons and exhibits an intron-less coding region.
