Studies on Plant Bile Pigments: Characterization of a Model for the Phytochrome Pr Chromophor
نویسنده
چکیده
Bile Pigments, Phytochrome, Chromophor Model The common A-dihydrobiliverdin chromophor proposed to be present in both phycocyanin and phytochrome Pr has been characterized by using octaethylbiliverdin and its A-dihydro derivative as model compounds. The UV-vis spectra for the free bases, cations, anions and zinc complexes are reported, and the related protonation-deprotonation equilibria have been studied. The data support the postulated structures for the biliproteid chromophor, and at the same time they indicate A-dihydrooctaethylbiliverdin to be a useful model.

Studies on Plant Bile Pigments-6. Photochemically Assisted Reaction of a Model for Phytochrome Interconversion A-dihydrobilindione with Nucleophiles As
From the A-dihydrobilindione 3. the pyridinium derivatives 6a,b and analogues therwf have been obtained by a formal nucleophilic substitution. The reaction is rationalized as a photochemically assisted oxidation of 3 with a subsequent regioselective addition of pyridine at C-5. By thermolysis. 6a.b yields back the parent bilin 3, together with an oxidation product. The significance of the react...

Phytochrome, the photomorphogenetic reaction center pigment of green plants and some algae, has been proposed recently to contain two chemically different chromophores in its P, and P,, forms, respectively (Grombein et al., 1975). P, contains an A-dihydrobilin chromophore (1) closely related to that of phycocyanin. For P,,, a violin (2) (or possibly purpurin) (Scheer et al., 1976) type chromoph...

متن کاملTheoretical studies of biliprotein chromophores and related Bile pigments by molecular orbital and ramachandran type calculations.
Ramachandran calculations have been used to gain insight into steric hindrance in bile pigments related to biliprotein chromophores. The high optical activity of denatured phycocyanin, as compared to phycoerythrin, has been related to the asymmetric substitution at ring A, which shifts the equilibrium towards the P-helical form of the chromophore. Geometric effects on the electronic structures ...
متن کاملSpectral Characterization and Proteolytic Mapping of Native 120-Kilodalton Phytochrome from Cucurbita pepo L.
A spectral, immunochemical, and proteolytic characterization of native 120-kilodalton (kD) phytochrome from Cucurbita pepo L. is presented and compared with that previously reported for native 124-kD phytochrome from Avena sativa. The molecule was partially purified ( approximately 200-fold) in the phytochrome-far red-absorbing form (Pfr) in the presence of the protease inhibitor, phenylmethyls...
