The budding yeast Saccharomyces cerevisiae has long proved to be a very useful model in cell biology. Its cell morphology is established and maintained at least in part by the cell wall, a rigid but dynamic structure that affords mechanical protection. Although fungal cell walls represent an unique phenomenon, recent progress in research has shown striking parallels between yeast and mammalian ...

Beta-1,2-linked mannosides (beta-Mans) are believed to contribute to Candida albicans virulence. The presence of beta-Mans has been chemically established for two molecules (phosphopeptidomannan [PPM] and phospholipomannan) that are noncovalently linked to the cell wall, where they correspond to specific epitopes. However, a large number of cell wall mannoproteins (CWMPs) also express beta-Man ...

The outer cell wall of the yeast Saccharomyces cerevisiae serves as the interface with the surrounding environment and directly affects cell-cell and cell-surface interactions. Many of these interactions are facilitated by specific adhesins that belong to the Flo protein family. Flo mannoproteins have been implicated in phenotypes such as flocculation, substrate adhesion, biofilm formation, and...

Mannoproteins in the walls of mnn9 cells of Saccharomyces cerevisiae were released by laminarinase, and purified by concanavalin A affinity chromatography and ion-exchange chromatography. Carbohydrate analysis revealed that they contained N-acetylglucosamine, mannose, and glucose. An antiserum raised against beta (1-6)-glucan reacted with four proteins with molecular masses of 66, 100, 155, and...
