When Is the Helix Conformation Restored after the Reverse Reaction of Phototropin?

Following the disruption of the covalent bond between the cysteine and flavin of Phot1LOV2-linker, the unfolded conformation of the linker folds with a time constant of 13 ms, which is considerably (similar to 10(4) times) slower than the helix formation rate measured for an alpha-helical polypeptide in solution.
