Analysis of Peptide Secondary Structures by Photoactivatable Amino Acid Analogues

Abstract

Photochemical cross-linking was applied to trap intramolecular interactions in peptides. The incorporation of diazirine-labeled amino acid analogues in combination with high-resolution mass spectrometry made it possible to catch reverse-turn conformations within peptides, exactly map their self-interacting surfaces, and discriminate between stable and transient interactions.
