Structural study of cell wall mannan of a Candida albicans (serotype A) strain.
The structure of the mannan of Candida albicans NIH A-207 strain (serotype A) was investigated by adopting mild acetolysis followed by enzymolysis with an Arthrobacter GJM-1 exo-alpha-mannosidase. The resultant oligosaccharides, from pentaose to octaose (where manp = D-mannopyranose), were identified as manp beta (1----2)manp alpha (1----2)manp alpha (1----2)manp alpha (1----2)manp, manp beta (1----2)manp beta (1----2)manp alpha (1----2)manp alpha (1----2)- manp alpha (1----2)manp, manp beta (1----2)manp beta (1----2)manp beta (1----2)manp alpha (1----2)manp alpha (1----2)manp alpha (1----2)manp and manp beta (1----2)manp beta (1----2)manp beta (1----2)manp beta (1----2)manp alpha (1----2)manp alpha (1----2)manp alpha (1----2)manp, respectively. Analyses of alpha-linked oligosaccharides obtained by acetolysis under conventional conditions gave the same oligosaccharides, from biose to heptaose, as those obtained from the mannans of C. albicans NIH B-792 (serotype B) and J-1012 (serotype A, formerly serotype C).
