Protein folding by specific pathway
WebbFor a protein to function appropriately, it must first achieve its proper conformation and location within the crowded environment inside the cell. Multiple chaperone systems are required to fold proteins correctly. In addition, degradation pathways participate by destroying improperly folded proteins. WebbAdvances in spectroscopy, protein engineering, and peptide synthesis have had a dramatic impact on the understanding of the structures and stabilities of transient folding …
