Аннотация: The Ca2+-regulated photoprotein obelin determines the luminescence of the marine hydroid Obelia longissima. Bioluminescence is initiated by calcium and appears as a result of the oxidative decarboxylation related to the coelenterazine substrate. The luciferase of the luminescent marine coral Renilla muelleri (RM) also uses coelenterazine as a substrate. However, three proteins are involved in the in vivo bioluminescence of these animals: luciferase, green fluorescent protein, and Ca2+-regulated coelenterazine-binding protein (CBP). In fact, CBP that contains one strongly bound coelenterazine molecule is the RM luciferase substrate in the in vivo bioluminescent reaction. Coelenterazine becomes available for oxygen and the reaction with luciferase only after binding CBP with calcium ions. Unlike Ca2+-regulated photoproteins, the coelenterazine molecule is not activated by oxygen in the CBP molecule. In this work, by means of quantum chemical methods the behavior of substrates in these proteins is analyzed. It is shown that coelenterazine can form different tautomers: CLZ(2H) and CLZ(7H). The formation of 2-hydroperoxy-coelenterazine is studied. According to the obtained data, these proteins use different forms of the substrates for the reaction. In obelin, the substrate is in the CLZ(2H) form that affords hydrogen peroxide. In RM, coelenterazine is in the CLZ(7H) form, and therefore, CBP is not activated by oxygen.

Ключевые слова (''Своб.индексиров.''): daily rhythm of grazing--fluorescence--microalgae--flowing-through cultivator--photoperiod--statistical spectral analysis
Аннотация: The circadian rhythm of grazing of microalgae by a laboratory culture of Ceriodaphnia quadrangula under continuous illumination was studied by continuous registration of chlorophyll fluorescence at the outlet of a flow-through cultivator. A culture of green alga Chlorella vulgaris was used as a feed. The data obtained were treated by the statistical spectral analysis. It was found that animals preliminarily grown under a 12 h light : 12 h dark regime and transferred to constant light showed two maxima in the circadian rhythm of grazing with periods of 0.7 and 1.1 h. Animals preliminarily grown under constant light showed no circadian rhythm of grazing. It was concluded that the circadian rhythm of grazing of C quadrangula has endogenous nature and can change according to light conditions.

Аннотация: Changes in absorption, fluorescence, phosphorescence, and delayed fluorescence spectra of erythrosin B are studied in the presence of bovine serum albumin at room temperature. Spectral and chronoscopic characteristics of the observed photophysical processes are defined. The binding of erythrosin B with the protein followed by spectral changes is demonstrated. Absorption and fluorescence spectra of the dye in the bound state are described, the binding mechanism is analyzed. The binding parameters of the dye-protein complex are estimated.
