Publication Abstract from PubMed

We report here the comparison of five classes of unnatural amino acid building blocks for their ability to be accommodated into an alpha-helix in a protein tertiary fold context. High-resolution structural characterization and analysis of folding thermodynamics yield new insights into the relationship between backbone composition and folding energetics in alpha-helix mimetics and suggest refined design rules for engineering the backbones of natural sequences.
