Yeast and hyphal walls of Candida albicans were extracted with sodium dodecyl sulfate (SDS). Some of the extracted proteins reacted with a specific β-1,6-glucan antiserum but not with a β-1,3-glucan antiserum. They lost their β-1,6-glucan epitope after treatment with ice-cold aqueous hydrofluoric acid, suggesting that β-1,6-glucan was linked to the protein through a phosphodiester bridge. When yeast and hyphal walls extracted with SDS were subsequently extracted with a pure β-1,3-glucanase, several mannoproteins that were recognized by both the β-1,6-glucan antiserum and the β-1,3-glucan antiserum were released. Both epitopes were sensitive to aqueous hydrofluoric acid treatment, suggesting that β-1,3-glucan and β-1,6-glucan are linked to proteins by phosphodiester linkages. The possible role of β-glucans in the retention of cell wall proteins is discussed.
