Cyanopeptolin
Cyanopeptolins are a class of oligopeptides produced by Microcystis and Planktothrix algae strains, and can be neurotoxic.[1][2][3] The production of cyanopeptolins occurs through nonribosomal peptides synthases (NRPS).[4]
Characteristics[]
Increased water temperatures, because of climate change and eutrophication of inland waters promote blooms of cyanobacteria, potentially threaten water contamination by the production of the toxic cyanopeptolin (CP1020).[1]
Exposure[]
Cyanopeptolin (CP1020) exposure in zebrafish affected pathways related to DNA damage, the circadian rhythm and response to light.[1]
