Paradoxical One-ion Pore Behavior of the Long β-Helical Peptide of Marine Cytotoxic Polytheonamide B
The cytotoxic 48-mer peptide, polytheonamide B (pTB), from a marine sponge forms a β(6.3)-helix with an inner diameter of 4 Å and a length of 45 Å, features that allow the selective permeation of monovalent cations across targeted cell membranes. To characterize this long, narrow pore, electrophysio...
