    Abstract

    Two glycoproteins have been isolated from the cell walls of baker's yeast. One is a glucan-protein complex which has been partially characterised as having a branched carbohydrate structure composed of chains of (1?3)-linked ß-d-glucosyl residues, some of which are attached by (1?6)-linkages to the main chain. Immobilization of this glycoprotein was achieved by covalent attachment to Sepharose, and the product was used to isolate a number of (1?3)-ß-d-glucan hydrolases from Helix pomatia, malted barley, and Basidiomycete QM806. The second glycoprotein, a mannan-protein complex, after immobilization, has been used in the purification of an a-d-mannosidase from jack-bean meal. © 1977.
