The correct order for molecular chaperone–mediated protein folding is:

I – exchange of ATP for ADP on chaperone

II – chaperone undergoes conformational change, which affects protein folding

III – chaperone binds to exposed hydrophobic residues on unfolded protein

IV – folded protein is released
