Characterizing folding pathways of large proteins that bind complex cofactors is challenging. The authors use optical tweezers to study the 542-residue FAD-binding lightsensor protein dCRY, identifying several intermediates and cofactor binding steps, and dissecting the role of FAD moieties in folding.
