Abstract
Beta sheets are inherently length-limited; adding residues to the ends of model β-sheets does not necessarily grow the β-sheet. Here, we present a method for extending β-sheets to any length with a stabilizing repeat unit containing cross-strand Trp residues. Beta ribbons as long as 35 residues (approaching 100 Å in length) are reported and characterized.
