The chromophore of phytochrome.
The chromophore of phytochrome, the plant photomorphogenic pigment, was cleaved from the associated protein. Chromatographic and spectral properties indicated that it was a bilitriene closely similar to but distinct from the chromophore of C-phycocyanin and allophycocyanin.
متن کاملChromophore structure in the photocycle of the cyanobacterial phytochrome Cph1.
The chromophore conformations of the red and far red light induced product states "Pfr" and "Pr" of the N-terminal photoreceptor domain Cph1-N515 from Synechocystis 6803 have been investigated by NMR spectroscopy, using specific 13C isotope substitutions in the chromophore. 13C-NMR spectroscopy in the Pfr and Pr states indicated reversible chemical shift differences predominantly of the C(4) ca...
متن کاملIn vitro assembly of phytochrome B apoprotein with synthetic analogs of the phytochrome chromophore.
Phytochrome B (PhyB), one of the major photosensory chromoproteins in plants, mediates a variety of light-responsive developmental processes in a photoreversible manner. To analyze the structural requirements of the chromophore for the spectral properties of PhyB, we have designed and chemically synthesized 20 analogs of the linear tetrapyrrole (bilin) chromophore and reconstituted them with Ph...
متن کاملSynthesis of phytochrome apoprotein and chromophore are not coupled obligatorily.
G Gardner and HL Gorton (1985 Plant Physiol 77: 540) demonstrated that gabaculine (5-amino-1,3-cyclohexadienylcarboxylic acid) inhibits the initial synthesis and resynthesis of spectrophotometrically detectable phytochrome in pea, maize, and oat. We show that the level of immuno-detectable phytochrome in pea is unaffected by the presence of gabaculine at a concentration that reduces spectrophot...
متن کاملBiliverdin reductase-induced phytochrome chromophore deficiency in transgenic tobacco.
Targeted expression of mammalian biliverdin IXalpha reductase (BVR), an enzyme that metabolically inactivates linear tetrapyrrole precursors of the phytochrome chromophore, was used to examine the physiological functions of phytochromes in the qualitative short-day tobacco (Nicotiana tabacum cv Maryland Mammoth) plant. Comparative phenotypic and photobiological analyses of plastid- and cytosol-...
