Chaperone
Chaperone — A protein that assists in the folding, assembly, and transport of other proteins and peptides without being part of the final structure.
What Is a Chaperone?
A molecular chaperone is a protein that assists the folding, assembly, and transport of other proteins and peptides without being part of the final structure. Chaperones prevent aggregation of unfolded or misfolded intermediates and are essential for correct folding of complex multi-disulfide peptides during recombinant production.
Peptide Relevance
- Inclusion body refolding: Chemical chaperones (arginine, glycerol) assist refolding of recombinant peptides from E. coli
- Pharmacological chaperones: Small molecules that stabilize misfolded proteins (enzyme replacement therapy concept)
- Chaperone peptides: Short sequences mimicking chaperone binding surfaces
