摘要：We investigated the antibacterial activity of Anemonia sulcata (Cnidaria, Anthozoa) tentacle andbody acidic extracts. Biochemical purification consisted of first step on solid phase Sep-Pak C8 column followed by several HPLC runs on C18 column using different conditions. Anti-Micrococcus lysodeikticus activity has been detected in 40 % acetonitrile fractions. The resulting purified molecule from tentacles had a molecular mass determined by MALDI-TOF mass spectrum of 4946,299 Da and has been completely sequenced. Its aa sequence revealed identity with the Neurotoxin 2 (ATX-II), a Na+ channel blocking toxins. Consequently, ATX-II appeared to display a dual role as toxin and as antibacterial.
