The mycotoxin antiamoebin has recently been shown to be a mixture of at least five closely related pep tide^'^^). Like alamethicins, antiamoebins fall in the class of peptaibol antibiotic^^,^), which are characterized by the presence of several Aib residues and a 1,2-aminoalcohol at the C-terminus.
