Polysaccharides of Cryptococcus neoformans are considered to have a role in the virulence of this encapsulated fungus. The structure has been determined for the most abundant polysaccharide, a glucuronoxylomannan of varying xylose and ester content. The structural complexity of the capsular material increases from serotype D to A to B to C, but even for the simplest capsule (type D), the immunodeterminants seem to occur only on the side chains. The interactions of some of these groups with antibodies is discussed

Comments, role: the degree of O-acetylation is 10,4 %. the O-acetyl groups are probably located at C-6 of the mannosyl residues of the backbone; chemical repeating unit frame was shifted in annotation for compatibility with structures elucidated by MS [Eukaryotic Cell 2007, 6: 1464-1473]
