|Section2= |Section3= }} Alamethicin's a peptide antibiotic, produced by the fungus Trichoderma viride. It contains the non-proteinogenic amino acid 2-aminoisobutyric acid (Aib), which strongly induces helical peptide structures. The peptide sequence's: Ac-Aib-Pro-Aib-Ala-Aib-Ala-Gln-Aib-Val-Aib-Gly-Leu-Aib-Pro-Val-Aib-Aib-Glu-Gln-Phl (Ac = acetyl, Phl = phenylalaninol) It's UV spectrum maxima at 265 and 257 nm. In cell membranes, it forms voltage-dependent ion channels by aggregation of four… (More on Alamethicin)
