Peptides composed of leucyl and lysyl residues (LK pep-tides) with different compositions and sequences were compared for their antibacterial activities usingcell wall-less bacteria of the classMollicutes(acholeplasmas, mycoplas-mas and spiroplasmas) as targets. The antibacterial activity of the amphipathica-helical peptides varied with their size, 15 residues beingthe optimal length, independent of the membrane hydrophobic core thickness and the amount of cholesterol.
