title: [Isolation and structure of an external glycoprotein of the cell wall of Torulopsis candida].
abstract: The treatment with ethylenediamine of Torulopsis candida yeast cell walls has permitted to isolate a mannoprotein. It has been possible to collect this glycoprotein in a pure state after separation of the different hydrosoluble products by gel filtrations and paper electrophoresis. This compound contains 62 per cent of mannose, 3 per cent of N-acetylglucosamine and 31 per cent of amino acids. The mannose units are attached by 1 leads to 2 linkage, short oligosaccharides are bound to serine of the peptide chain by O-glycosidic linkages while polysaccharides are attached to asparagine of this peptide chain by a N glycosidic linkages probably through the intermediate of chitobiose.
