| + | We have examined whether parallel beta-sheet secondary structure becomes more stable as the number of beta-strands increases, via comparisons among peptides designed to adopt two- or three-stranded parallel beta-sheet conformations in aqueous solution. Our three-strand design is the first experimental model of a triple-stranded parallel beta-sheet. Analysis of the designed peptides by nuclear magnetic resonance (NMR) and circular dichroism (CD) spectroscopy supports the hypothesis that increasing the number of beta-strands, from two to three, increases the stability of the parallel beta-sheet. We present the first experimental evidence for cooperativity in the folding of a triple-stranded parallel beta-sheet, and we show how minimal model systems may enable experimental documentation of characteristic properties, such as CD spectra, of parallel beta-sheets. | ||
