(A) Cryo-etch SEM image of KLVFFAE nanotubes assembled in acidic conditions[28]. (B) Bundling of positively charged nanotubes upon addition of sodium sulfate [60]. In the bilayer cartoon of KLVFFAE nanotubes, the peptides are organized as anti-parallel β-sheets placing hydrophilic lysine side chains (blue) at both the solvent exposed interface and buried in the bilayer interface. Leucine and protonated glutamic acids are drawn in grey space filling models. The remaining residues are drawn as sticks, with front peptide (grey) and back peptide (white).
