摘要:
Back to the fold: A new method to determining the stability of a β hairpin is described. A β hairpin forming sequence (β4) is introduced into native ubiquitin (see structure) enabling the contribution to protein stability of this structural motif to be estimated. This data provides both an upper limit on stability for autonomously folding β hairpins, and a spectroscopic reference state for estimating the stability of related peptides in solution.
