  1. Alamethicin

    Alamethicin is a peptide antibiotic, produced by the fungus Trichoderma viride. It belongs to peptaibol peptides which contain the non-proteinogenic amino acid residue Aib. This residue strongly induces formation of alpha-helical structure. The peptide sequence is: Ac-Aib-Pro-Aib-Ala-Aib-Ala-Gln-Aib-Val-Aib-Gly-Leu-Aib-Pro-Val-Aib-Aib-Glu-Gln-Phl In cell membranes, it forms voltage-dependent ion channels by aggregation of four to six molecules.
