Research Abstract

Mycosporine-like amino acids (MAAs) are water-soluble pigments that absorb UV radiation of 280 to 340 nm. In this study, novel MAAs were purified from the terrestrial cyanobacterium Nostoc commune, and their chemical structures were characterized. These unique glycosylated MAAs have multiple roles as a UV protectant and an antioxidant relevant to anhydrobiosis in this organism. Moreover, glycosylated MAA patterns could be a feasible chemotaxonomic marker for the characterization of the morphologically indistinguishable N. commune.
