Overview
Determining peptide three-dimensional structures has been essential for understanding function and designing therapeutics.
Key Methods
- X-ray crystallography: High-resolution atomic structures
- NMR spectroscopy: Solution-state dynamics and conformations
- Circular dichroism: Secondary structure content
- Cryo-EM: Near-atomic resolution without crystallization
Milestones
- 1951: Pauling proposes alpha-helix and beta-sheet
- 1960s: First peptide crystal structures
- 1980s: NMR solution structures
- 2010s: Cryo-EM revolution for peptide complexes
Impact
Structural knowledge enables rational peptide design, understanding of aggregation, and mechanism-based drug development.
