Structure of acidic oligosaccharides isolated from pronase-treated glycoprotein of bonnet-monkey (Macaca radiata) cervical mucus. The major glycoprotein component of cervical mucus of bonnet monkey was treated with Pronase, and the enzyme-resistant glycoprotein purified by gel filtration on Sepharose 4B followed by DEAE-cellulose chromatography. Alkaline-borohydride cleavage of the carbohydrate chains gave a mixture of neutral and acidic oligosaccharides. Seven acidic oligosaccharides were characterized by chemical and enzymic procedures; their proposed structures are: alpha NeuAc(2----3)-[beta GalNAc(1----4)]beta Gal(1----4)GlcNAc(1----6)[alpha Fuc(1----2)beta Gal(1----3)]GalNAc-ol; alpha Fuc(1----2)beta Gal(1----3)/6)[alpha NeuAc(2----3)beta Gal(1----4)GlcNAc(1----3)/6)]GalNAc-ol; alpha GalNAc(1----3)beta Gal(1----3)[alpha NeuAc(2----3)beta Gal(1----4)GlcNAc(1----6)]GalNAc-ol; beta GlcNAc(1----3)[alpha Fuc(1----2)]beta Gal(1----3)[alpha NeuAc(2----6)]GalNAc-ol; beta Gal(1----3)-[alpha NeuAc(2----6)]GalNAc-ol; alpha NeuAc(2----6)GalNAc-ol; and beta Gal3SO3(1----4) GlcNAc(1----6)[alpha Fuc(1----2)beta Gal(1----3)]GalNAc-ol.
