The cyanobacterial UV-absorbing pigment scytonemin displays radical-scavenging activity
Open accessAbstract
Scytonemin is a 544-Da hydrophobic pigment that can absorb UV-A radiation. It is present in cyanobacterial sheaths and is thought to function as a UV protectant. In this study, scytonemin was purified from the terrestrial cyanobacterium Nostoc commune, and its radical-scavenging activity was characterized. The purified scytonemin quenched an organic radical in vitro and accounted for up to 10% of the total activity of an ethanol extract of N. commune. These results suggest that the extracellular UV-absorbing pigment scytonemin has multiple roles, functioning as a UV sunscreen and an antioxidant relevant to anhydrobiosis in N. commune.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
