Antimicrobial peptide with modest activity (PubMed:16890198, PubMed:23137541). Active against the Gram-positive bacterium L.monocytogenes (MIC=22.64 ug/ml), B.megaterium (MIC=10 uM), B.mycoides, B.subtilis, M.luteus (MIC=40 uM), M.phlei, and S.aureus, and the Gram-negative bacterium E.coli (MIC=7.66 ug/ml) and P.aeruginosa (PubMed:16890198, PubMed:23137541). Shows moderate affinity to the negatively charged (POPC/DOPG 3:1) lipid vesicles (PubMed:23137541). The peptide interacts with the surface of DPC micelles by two alpha-helical regions (PubMed:23137541). It does not interact with the zwitterionic (POPC) lipid vesicles, which model membranes of eukaryotic cells (PubMed:23137541). Isolated from mesoglea. The peptide interacts with the surface of DPC micelles by two alpha-helical regions. Belongs to the sea anemone type 1 potassium channel toxin family. Shows similarity to potassium channel (Kv) toxins, but does not possess the 'functional dyad' element required for binding to Kv channels. As a consequence, it may not be a channel blocker.
