| Preparation and Properties of Chromopeptides from the Pfr Form of Phytochrome  | | | Abstract
| Chromopeptides were prepared from the Pfr form o f phytochrome by pepsin digestion. After separation from colorless peptides and Pr peptides by column chromatography, spectral characteristics of this Pfr peptide were determined (A^ax = 610nm, A£ax = 380nm in acid methanol). Irradiation of Pfr peptide produces Pr peptide without liberation of a detectable compound. The Pfr peptide is more sensitive to oxidation and reduction than the Pr peptide. Oxidation with iodine and reduction with dithionite leads to partial chemoconversion o f the Pfr peptide to the Pr peptide. The results favor the model o f cis-trans isomerization for the Pr ^ Pfr transformation. | | |
