TI  - Structural characterization of the released polysaccharide of
      desiccation-tolerant Nostoc commune DRH-1.
PG  - 974-82
AB  - The structure of the viscous extracellular polysaccharide (glycan) of
      desiccation-tolerant Nostoc commune DRH-1 was determined through chromatographic 
      and spectroscopic methods. The polysaccharide is novel in that it possesses a
      1-4-linked xylogalactoglucan backbone with D-ribofuranose and
      3-O-[(R)-1-carboxyethyl]-D-glucuronic acid (nosturonic acid) pendant groups. The 
      presence of D-ribose and nosturonic acid as peripheral groups is unusual, and
      their potential roles in modulating the rheological properties of the glycan are 
      discussed. Nosturonic acid was present in the glycans of N. commune from diverse 
      geographic locations, suggesting that this uronic acid is an integral component
      of this cosmopolitan anhydrophile.
