Abstract:
:Sulfotransferase activity catalyzing the transfer of sulfate ester group from 3'-phosphoadenosine-5'-phosphosulfate to salivary mucins was found associated with Golgi-rich membrane fraction of rat submandibular salivary glands. Alkaline borohydride reductive cleavage of the synthesized 35S-labeled glycoprotein led to the liberation of the label into reduced acidic oligosaccharides. Most of the label was found incorporated in four oligosaccharides. These were identified as sulfated tri-, penta-, hepta- and nonasaccharides. The trisaccharide was characterized as SO3H,6GlcNAc beta 1,3Gal beta 1,3GalNac-o1, the pentasaccharide as SO3H,6GlcNAc beta 1,3Gal beta 1,4GlcNAc beta 1,3(NeuAc alpha 2,6) GalNAc-o1 and heptasaccharide as SO3H,6Gal beta 1,4GlcNAc beta 1,6(Fuc alpha 1) 2Gal beta 1,4GlcNAc beta 1,3Gal beta 1,3)GalNAc-o1.
