How do cofactors modulate protein folding?
Cofactors are essential components of many proteins for biological activity. Characterization of several cofactor-binding proteins has shown that cofactors often have the ability to interact specifically with the unfolded polypeptides. This suggests that cofactor-coordination prior to polypeptide folding may be a relevant path in vivo. By binding before folding, the cofactor may affect both the mechanism and speed of folding. Here, we discuss three different cofactors that modulate protein-folding processes in vitro.
