Fig 4. Helical wheel diagrams of piscidins 6 and 7.
(a) Striped bass piscidin 6. (b) White bass piscidin 6. (c) Striped bass piscidin 7. An amphipathic nature is suggested in all three piscidins by the alignment of the hydrophobic residues (circled amino acids) along one side of the helix and the hydrophilic residues along the other.
