HPA3NT3 PEPTIDE HAVING ANTIALGAE ACTIVITY AGAINST ORGANISM INDUCED RED TIDE AND THE USE OF THE SAME

摘要

PURPOSE: An organism-derived natural anti-red tidal peptide HPA3NT3 is provided to ensure selective anti-red tidal activity without cytotoxicity. CONSTITUTION: An HPA3NT3 peptide has an amino acid sequence of sequence number 3. The HPA3NT3 peptide has a sequence in which 9th amino acid, glutamic acid(Glu) and 13th amino acid, serine of HPA3 peptide of sequence number 2 are substituted. The HPA3NT3 peptide has an anti-red tidal activity to C. polykrikoides, C. marina, or H. akashiwo. An anti-red tidal composition contains the HPA3NT3 peptide as an active ingredient.
