Joining the fold : Micrometer‐long and nanometer‐thin fibers of four‐helix bundles are formed by the folding‐mediated assembly of disulfide‐linked helix–loop–helix polypeptides (see picture). Fibers form both as a result of heteroassociation at neutral pH and homoassociation at acidic pH values. The heteroassociated fibers also assemble into nanorings with a diameter up to 5 μm.
