Аннотация: The study addresses the ability of luminous bacteria of different taxa (Photobacterium leiognathi, Photobacterium phosphoreum, Vibrio harveyi, Vibrio fischeri) to synthesize polyesters of hydrocarbon acids (polyhydroxyalkanoates, PHAs) as storage macromolecules. The screened strains widely varied in their PHA productivity. Conditions for attaining high polymer yields (including two- and three-component polymers) in batch culture have been determined. The attained polymer yields reached 40-70% of dry cell biomass. The results suggest a conclusion that luminous microorganisms can be considered as producers of multi-component PHAs.

Аннотация: Ca2+-regulated photoproteins use a noncovalently bound 2-hydroperoxycoelenterazine ligand to emit light in response to Ca2+ binding. To better understand the mechanism of formation of active photoprotein from apoprotein, coelenterazine and molecular oxygen, we investigated the spectral properties of the anaerobic apo-obelincoelenterazine complex and the kinetics of its conversion into active photoprotein after exposure to air. Our studies suggest that coelenterazine bound within the anaerobic complex might be a mixture of N7-protonated and C2() anionic forms, and that oxygen shifts the equilibrium in favor of the C2() anion as a result of peroxy anion formation. Proton removal from N7 and further protonation of peroxy anion and the resulting formation of 2-hydroperoxycoelenterazine in obelin might occur with the assistance of His175. It is proposed that this conserved His residue might play a key role both in formation of active photoprotein and in Ca2+-triggering of the bioluminescence reaction.

Аннотация: Many proteins require a non-covalently bound ligand to be functional. How ligand binding affects protein conformation is often unknown. Here we address thermal unfolding of the free and ligand-bound forms of photoprotein obelin. Fluorescence and far-UV circular dichroism ( CD) data show that the various ligand-dependent conformational states of obelin differ significantly in stability against thermal unfolding. Binding of coelenterazine and calcium considerably stabilizes obelin. In solution, all obelin structures are similar, except for apo-obelin without calcium. This latter protein is an ensemble of conformational states, the populations of which alter upon increasing temperature. (C) 2012 Federation of European Biochemical Societies.

Аннотация: The technology of real-time imaging in living cells is crucial for understanding of intracellular events. For this purpose, bioluminescent reporters have been introduced as sensitive and convenient tools. Metridia luciferase (MLuc) from the copepod Metridia longa is a coelenterazine-dependent luciferase containing a natural signal peptide for secretion. We report the high-active MLuc mutants with deletion of the N-terminal variable part of amino acid sequence. The MLuc variants were produced in Escherichia coil cells, converted to an active protein, and characterized. We demonstrate that the truncated MLucs have significantly increased bioluminescent activity as against the wild type enzyme but substantially retain other properties. One of the truncated variants of MLuc was transiently expressed in HEK 293 cells. The results clearly suggest that the truncated Metridia luciferase is well suited as a secreted reporter ensuring higher detection sensitivity in comparison with a wild type enzyme.

Ca(2+)-regulated photoprotein -- bioluminescence -- dual-color assay
Аннотация: Two kinds of Ca(2+)-regulated photoprotein obelin with altered color of bioluminescence were obtained by active-center amino acid substitution. The mutant W92F-H22E emits violet light (lambda(max)=390 nm) and the mutant Y139F emits greenish light (lambda (max)=498 nm), with small spectral overlap, both display high activity and stability and thus may be used as reporters. For demonstration, the mutants were applied in dual-color simultaneous immunoassay of two gonadotropic hormones-follicle-stimulating hormone and luteinizing hormone. Bioluminescence of the reporters was simultaneously triggered by single injection of Ca(2+) solution, divided using band-pass optical filters and measured with a two-channel photometer. The sensitivity of simultaneous bioluminescence assay was close to that of a separate radioimmunoassay.

Аннотация: Bioluminescence in the sea pansy Renilla involves two distinct proteins, a Ca2+-triggered coelenterazine-binding protein (CBP), and Renilla luciferase. CBP contains one tightly bound coelenterazine molecule, which becomes available for reaction with luciferase and O-2 only subsequent to Ca2+ binding. CBP belongs to the EF-hand superfamily of Ca2+-binding proteins and contains three "EF-hand" Ca2+-binding sites. The overall spatial structure of recombinant selenomethionine-labeled CBP determined at 1.7 angstrom, is found to approximate the protein scaffold characteristic of the class of Ca2+-regulated photoproteins. Photoproteins however, catalyze molecular oxygen addition to coelenterazine producing a 2-hydroperoxycoelenterazine intermediate, which is stabilized within the binding cavity in the absence of Ca2+. Addition of Ca2+ triggers the bioluminescence reaction. However in CBP this first step of oxygen addition is not allowed. The different amino acid environments and hydrogen bond interactions within the binding cavity are proposed to account for the different properties of the two classes of proteins.

Аннотация: The crystal structure of the Ca2+-loaded coelenterazine binding protein from Renilla muelleri in its apo-state has been determined at resolution 1.8 angstrom. Although calcium binding hardly affects the compact scaffold and overall fold of the structure before calcium addition, there are easily discerned shifts in the residues that were interacting with the coelenterazine and a repositioning of helices, to expose a cavity to the external solvent. Altogether these changes offer a straightforward explanation for how following the addition of Ca2+, the coelenterazine could escape and become available for bioluminescence on Renilla luciferase. A docking computation supports the possibility of a luciferase-binding protein complex.

Аннотация: Time-resolved fluorescence was used to directly measure the energy transfer rate constant in the protein-protein complex involved in the yellow bioluminescence of Vibrio fischeri, strain Y1. In this reaction the putative donor is the fluorescent transient intermediate, luciferase hydroxyflavin, which exhibits a major fluorescence lifetime of the bound flavin of 10 ns. On addition of the acceptor, the V. fischeri yellow fluorescence protein containing either FMN or riboflavin as ligand, a rapid decay time, 0.25 ns, becomes predominant. The same results are observed using rec-luciferase from Photobacterium leiognathi to produce the donor. Because of favorable spectral separation in this system, this rapid decay rate of 4 ns(-1), can be directly equated to the energy transfer rate. This rate is ten times higher than the rate previously observed in the Photobacterium luciferase hydroxyflavin-lumazine protein, donor-acceptor system, derived from emission anisotropy measurements. This ten-times ratio is close to the ratio of spectral overlaps of the donor fluorescence with the acceptor absorption, between these two systems, so it is concluded that the topology of the protein complexes in both cases, must be very similar. Energy transfer is also monitored by the loss of steady-state fluorescence intensity at 460 nm of the donor, on addition of the acceptor protein. A fluorescence titration indicates that luciferase hydroxyflavin and the yellow protein complex with a 1:1 stoichiometry with a K-d of 0.7 mu M (0 degrees C). These parameters account for the bioluminescence spectral shifting effects observed in these reactions.

Аннотация: The kinetics of inactivation of luciferases from four species of luminescent bacteria by the thiol reagent N-ethylmaleimide were investigated The dependencies of inactivation on ionic strength differed among the enzymes. Increasing the molarity of the buffer increased the rate of inactivation of all luciferases except that of Vibrio harveyi. Modification of Photobacterium phosphoreum luciferase decreased the maximal intensity of bioluminescence, whereas modification of Photobacterium leiognathi and Vibrio fischeri luciferases in high ionic strength buffers decreased the maximal intensity of bioluminescence and changed the luminescence decay rate constant. High ionic strength apparently alters the conformational states of the luciferases.

Аннотация: Approximately 100 fish belonging to 24 families and several representatives of cephalopods, prawns, and euphausiids were investigated for the presence of luminescent bacteria. Species identification of isolated luminescent bacteria was performed, and the frequency and ratio of their occurrence in the gastrointestinal microflora of marine animals were determined. Luminescent bacteria occurred in 23 - 65% of the fish, depending on the habitat depth, and their ratio varied from 8 to 60% of the total gastrointestinal microflora of fish. The free-living luminescent bacteria were found in 50% of the seawater samples from depths down to 1000 m. The luminescent bacterium Photobacterium phosphoreum was dominant among the isolated cultures.

bacterial luciferase -- temperature -- activation energy
Аннотация: Effects of temperature on bioluminescent patterns of luciferases from luminescent bacteria Vibrio harveyi, Vibrio fischeri, Photobacterium leiognathi, and Photobacterium phosphoreum were studied. The highest luminescence level was observed at 15-25 degrees C for the luciferase from P. phosphoreum, at 20-30 degrees C for the V. fischeri and P. leiognathi enzymes, and at 30-37 degrees C for the enzyme from V. harveyi. All the luciferases were significantly stabilized at increased salt concentrations, at low pH values, or in the presence of dithiothreitol (DTT) and EDTA. The addition of DTT and EDTA affected the reversible stage of enzyme inactivation, while salts reduced the rate of the irreversible stage. A peak corresponding to aggregated protein was detected by gel chromatography of irreversibly inactivated luciferase. Activation energies were calculated for each luciferase in bioluminescent reactions with decanal, dodecanal, tetradecanal, and without aldehydes. The activation energy of the reaction with tetradecanal was much lower than those with the other aldehydes. The temperature dependence of the lifetime of the long-lived reaction intermediate showed that in the 10-30 degrees C interval all the luciferases, except for the enzyme from V. harveyi, have only one active form.

Аннотация: Luminescence and growth responses of the recombinant strain Escherichia coil Z905 (Ap(r)Lux(+)) to different concentrations of ampicillin depended on the source of carbon and energy. When glycerol was used as the substrate, the intensity of luminescence rose with the ampicillin concentration in the medium. Glucose caused catabolite repression of cell luminescence up to the late stationary phase, and ampicillin enhanced this effect. The feasibility of controlling the expression of cloned lux genes was shown.

Higher luminous fungi -- Neonothopanus nambi -- ionizing irradiation -- reactive oxygen species -- lipid peroxidation
Аннотация: The luminescent system of higher luminous fungi is not fully understood and the enzyme/substrate pair of the light emission reaction has not been isolated. It was suggested that luminescence of fungi involves oxidase-type enzymes, and reactive oxygen species are important for fungal light production. Generation of reactive oxygen species can be stimulated by ionizing irradiation, which has not been studied for luminous fungi. We report the effect of X-irradiation on the luminescence of fungus Neonothopanus nambi. Experiments were performed withmyceliumon a home-built setup based on an X-ray tube and monochromator/photomultiplier tube. Application of X-rays does not change the emission spectrum, but after approximately 20 min of continuous irradiation, light production from unsupported mycelium starts growing and increases up to approximately five times. After peaking, its level decreases irrespective of the presence of X-irradiation. After staying at a certain level, light production collapses to zero, which is not related to the drying of the mycelium or thermal impact of radiation. The observed shape of kinetics is characteristic of a multistage and/or chain reaction. The time profile of light production must reflect the current levels of radicals present in the system and/or the activity of enzyme complexes involved in light production.

Аннотация: The peroxidase and catalase activities in the mycelium of luminous basidiomycetes Armillaria borealis and Neonothopanus nambi in normal conditions and under stress were compared. An increase in the luminescence level was observed under stress, as well as an increase in peroxidase and catalase activities. Moreover, the peroxidase activity in extracts of A. borealis mycelium was found to be almost one and a half orders of magnitude lower, and the catalase activity more than two orders of magnitude higher in comparison with the N. nambi mycelium. It can be suggested that the difference between the brightly luminescent and dimly luminescent mycelium of N. nambi is due to the content of (HO2)-O-2 or other peroxide compounds.

luminescence -- luminous higher fungi -- mycelium
Аннотация: There are higher fungi that emit visible light; however, little is known about their requirements for good growth and bright luminescence. Knowledge of these requirements is extremely important for maintaining fungal cultures in laboratory conditions and preparation of luminous mycelia for research purposes. Luminous higher fungi Panellus stipticus, Armillaria sp. and Neonothopanus nambi isolated from different climatic areas and maintained in CCIBSO 836 (Collection of IBP SB RAS, Russia) were used for experiments. Techniques for static and submerged cultivation of mycelia of higher fungi have been developed and optimized for the production of samples of aerial and globular mycelia with prolonged and stable luminescence. We investigated the growth characteristics and luminescence of mycelia cultivated in/on different nutrient media, and the effects of deionized water and mechanical damage on the light emission of mycelia. An increase in luminescence intensity of fungal mycelia can be obtained during cultivation of fungi on a nutrient medium with a certain composition. A significant increase in light emission from N. nambi mycelium can also be obtained after its incubation in water and mechanical damage. The light emission from N. nambi mycelium was greatly enhanced after these treatments, in contrast to the mycelia of Armillaria sp. or P. stipticus. Cultivation conditions that enable growing mycelia with high levels of luminescence will expedite further studies to gain a better understanding of fungal bioluminescence.
