DRAMP18189

    • Function

    • Amphipathic peptide that possesses relatively strong activities against Gram-positive bacteria and a fungus, but has very weak antimicrobial activities against Gram-negative bacteria. Also exhibits mild hemolytic activities against human erythrocytes.Forms an alpha-helical membrane channel in the prey.
