Photosynthetic apparatus of cucumber and pea plants grown under red light with discrete or continuous spectra / E. N. Zavorueva [et al.] // Russian Journal of Plant Physiology. - 1996. - Vol. 43, Is. 2. - P191-199 . - ISSN 1021-4437

And thermoinduced changes in fluorescence yield -- Cucumis sativum -- Photo -- Photophosphorylation -- Pigments -- Pisum sativum
Аннотация: The effect of light sources with discrete or continuous spectra of red light (50 W/m2, 600-700 nm) on the structural and functional characteristics of chloroplasts were studied in leaves of cucumber (Cucumis sativum L.) plants, which die under strong red light, and pea (Pisum sativum L.) plants, which tolerate red light under the same conditions. Leaf condition was assessed by measuring thermo-and photoinduced changes in the chlorophyll fluorescence yield and the photochemical and photophosphorylating activities of the chloroplasts. Different responses of the pigment apparatus of pea and cucumber plants to red light with continuous or line spectra were revealed. Pea plants responded to discrete-spectrum light by changing P700 content, the ratio of antenna chlorophyll to P700, and the position of the low-temperature peak of the temperature-induced chlorophyll fluorescence yield. In cucumber plants, disturbances in the energy transfer from the short-wavelength pigments to chlorophyll a were observed. In both plants, the effects of line spectrum light on the pigment apparatus were reversible; the ratio of cyclic to noncyclic photophosphorylation, photosynthetic control, and the extent of the coupling of photosynthetic electron transport to photophosphorylation did not change compared to the control light. The need for examining the line spectra of light sources for growing plants under moderate intensities of artificial light (about 50 W/m2 of photosynthetically active radiation) is discussed.

Аннотация: In this review we summarize the progress made towards understanding the role of protein-protein interactions in the function of various bioluminescence systems of marine organisms, including bacteria, jellyfish and soft corals, with particular focus on methodology used to detect and characterize these interactions. In some bioluminescence systems, protein-protein interactions involve an "accessory protein" whereby a stored substrate is efficiently delivered to the bioluminescent enzyme luciferase. Other types of complexation mediate energy transfer to an "antenna protein" altering the color and quantum yield of a bioluminescence reaction. Spatial structures of the complexes reveal an important role of electrostatic forces in governing the corresponding weak interactions and define the nature of the interaction surfaces. The most reliable structural model is available for the protein-protein complex of the Ca2+-regulated photoprotein clytin and green-fluorescent protein (GFP) from the jellyfish Clytia gregaria, solved by means of X-ray crystallography, NMR mapping and molecular docking. This provides an example of the potential strategies in studying the transient complexes involved in bioluminescence. It is emphasized that structural studies such as these can provide valuable insight into the detailed mechanism of bioluminescence.

Ultrafast fluorescence relaxation spectroscopy of 6,7-dimethyl-(8-ribityl)-lumazine and riboflavin, free and bound to antenna proteins from bioluminescent bacteria / V. N. Petushkov [et al.] // Journal of Physical Chemistry B. - 2003. - Vol. 107, Is. 39. - P10934-10939 . - ISSN 1520-6106

Аннотация: The solvation dynamics of interesting bioluminescent chromophores have been determined, using subpicosecond and wavelength-resolved fluorescence spectroscopy, in combination with global analysis of the multidimensional data sets. The systems investigated comprise the free ligands 6,7-dimethyl-(8-ribityl)-lumazine (lumazine) and riboflavin in an aqueous buffer and both ligands when noncovalently bound to two bacterial bioluminescent antenna proteins: lumazine protein (from Photobacterium leiognathi) and the blue fluorescent protein (from Vibrio fischeri Y1). Fluorescence spectral relaxation of the free ligands is complete within a few picoseconds. Subsequently, the fluorescence intensity increases by ?7% on a time scale of 15-30 ps. Fluorescence spectral relaxation of the protein-bound ligands is largely complete within 1 ps but reveals a small red shift with a minor, but distinctly longer, relaxation time than that of the free ligands, which is tentatively assigned to the relaxation of protein-bound water in the vicinity of the excited chromophore.

Interaction of Photobacterium leiognathi and Vibrio fischeri Y1 luciferases with fluorescent (antenna) proteins: Bioluminescence effects of the aliphatic additive / V. N. Petushkov [et al.] // Biochemistry. - 1996. - Vol. 35, Is. 37. - P12086-12093, DOI 10.1021/bi9608931 . - ISSN 0006-2960

Аннотация: The kinetics of the bacterial bioluminescence reaction is altered in the presence of the fluorescent (antenna) proteins, lumazine protein (LumP) from Photobacterium or the yellow fluorescence proteins (YFP) having FMN or Rf bound, from Vibrio fischeri strain Y1. Depending on reaction conditions, the bioluminescence intensity and its decay rate may be either enhanced or strongly quenched in the presence of the fluorescent proteins. These effects can be simply explained on the basis of the same protein-protein complex model that accounts for the bioluminescence spectral shifts induced by these fluorescent proteins. In such a complex, where the fluorophore evidently is in proximity to the luciferase active site, it is expected that the on off rate of certain aliphatic components of the reaction should be altered with a consequent shift in the equilibria among the luciferase intermediates, as recently elaborated in a kinetic scheme. These aliphatic components are the bioluminescence reaction substrate, tetradecanal or other long-chain aldehyde, its carboxylic acid product, or dodecanol used as a stabilizer of the luciferase peroxyflavin. No evidence can be found for the protein- protein interaction in the absence of the aliphatic component.

Аннотация: Luminous organisms use different protein-mediated strategies to modulate light emission color. Here, we report the transient-state kinetic studies of the interaction between photoprotein clytin from Clytia gregaria and its antenna protein, cgreGFP. We propose that cgreGFP forms a transient complex with Ca2+-bound clytin before the excited singlet state of the coelenteramide product is formed. From the spectral distribution and donor-acceptor separation distance, we infer that clytin reaction intermediates may interact only with the middle side part of cgreGFP.
