Folding
Folding — The process by which a peptide or protein assumes its functional three-dimensional structure from a linear amino acid chain.
What Is Peptide Folding?
Folding is the process by which a linear peptide chain adopts its biologically active three-dimensional conformation. Folding is driven by the hydrophobic effect, hydrogen bonds, salt bridges, van der Waals interactions, and disulfide bond formation. Most short peptides do not fold stably; constrained peptides (cyclic, stapled) have defined folds.
Folding Factors
- Oxidative folding: Disulfide bond formation guides folding of cysteine-rich peptides
- Misfolding: Incorrect folding leads to aggregation or fibrillation
- Chaperones: Assist folding of complex multi-domain proteins; less relevant for short peptides
