The amino acid sequence of a peptide fragment of a peptide toxin isolated from the blue-green algae, Microcystis aeruginosa, is D-Ala-L Leu-erythro-β-methyl-D-isoAsp-L Ala-Baa-D-Glu, where Baa is a novel β-amino acid; the toxin is monocyclic, and the position of an N-methyldehydroalanine residue has been tentatively established.
