#Unit 6. System Physiology – Plant
  1. D-ring of the chromophore in the Pr form exist in the β-hairpin form changes conformation to an α-helix by inducing red-light
  2. the structure of the α helix region of Pr is changed to an β-hairpin during the conversion of Pr to Pfr
  3. C-ring of the chromophore in the Pfr form exist in the β-hairpin form changes conformation to an α-helix by inducing red-light and conversion of pr to pfr takes place
  4. By absorbing red light conversion of Pr to Pfr, β1-region of the chromophore changes conformation to an α-helix
