    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 (approximately 10(4) times) slower than the helix formation rate measured for an alpha-helical polypeptide in solution.
