Bold underline indicates disulfide bond. Net charge is at neutral pH. Superscript d after the amino acid represents the d-enantiomer; all other amino acids are L-form. Parentheses indicate amino acids that are cyclized. O, ornithine; B, diaminobutyrate; U, α-aminoisobutyric acid; Fol, phenylalaninol. Peptides Phd1-3, MPhd1-3 and LL37 have COOH at the C-terminus. LL37 sequence was taken from ref (3). The sequences of melittin, alamethicin and gramicidin A were taken from ref (32) gramicidin S and polymyxin B were taken from ref (37).
