SNP -- PEXT reaction -- obelin -- luciferase -- bioluminescent microassay
Аннотация: A method for single nucleotide polymorphism identification was developed, which was based on the primer extension reaction (PEXT) followed by bioluminescent solid-phase microassay. Recombinant Ca2+-regulated photoprotein obelin and coelenterazine-dependent Renilla muelleri luciferase were used as reporters. The study was performed as an example of SNP genotyping of the human F5 gene encoding human Factor V Leiden polymorphism 1691 G -> A (R506Q). Genomic DNA was amplified by PCR using primers flanking polymorphic site of 140 base pairs. PCR products were used as templates for two PEXT reactions using two primers containing 3'-terminal nucleotides, which were complementary to either normal or mutant alleles. If the template and allele-specific primer were completely complementary, the latter was elongated with DNA polymerase. The resulting extension product contained biotin residue due to the presence of biotinylated deoxyuridine triphosphate (B-dUTP) in the reaction mixture. The products were analyzed using obelin-streptavidin conjugates. The optimal PEXT-reaction conditions were found, which ensured a high reliability of SNP genotyping. A new approach to simultaneously revealing both alleles in one well was developed using two bioluminescent reporters. The efficiency of the proposed approach was shown in the study of clinical DNA samples.

Ca2+-triggered coelenterazine-binding protein (CBP) -- Renilla muelleri luciferase -- Bioluminescent solid-phase microassay
Аннотация: The recombinant Ca2+-triggered coelenterazine-binding protein (CBP) from Renilla muelleri was investigated as a biospecifically labeled molecule for in vitro assay applications. The protein was shown to be stable in solutions in the frozen state, as well as stable under heating and to chemical modifications. Conjugates with biotin, oligonucleotide, and proteins were obtained and applied as biospecific molecules in a solid-phase microassay. CBP detection was performed with intact (no modifications were made) Renilla luciferase in the presence of calcium, and the detection limit was found to be 75 amol. Model experiments indicate that this approach shows much promise, especially with regard to the development of multianalytical systems.

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: Translation of apoobelin mRNA in a cell-free wheat germ translation system in the presence of coelenterazine and molecular oxygen results in cotranslational formation of active photoprotein. Active obelin formation is recorded by its luminescence, either direct in the translation mixture in the presence of coelenterazine and calcium ions or in aliquots from the translation mixture. In the second case translation is carried out with coelenterazine and EGTA. Registration of the translation course by luminescence of the synthesized product in both cases allows use of apoobelin mRNA at very low concentrations as an internal marker for immediate measure of protein biosynthesis activity of in vitro translation systems. It is shown that the simultaneous translation of any other mRNA does not affect translation of photoprotein mRNAs under standard conditions. Continuous registration of luminescence in a cuvette of a liquid scintillation counter in photon-counting mode varies the time of signal accumulation in a wide temporal range, thus increasing the numerical values of the recorded signals. Registration of photoprotein luminescence during translation can be used to obtain additional information about the translation process, for example codon reading speed, about protein folding, and about the formation of active proteins on ribosomes.

Аннотация: Using site directed mutagenesis, the conservative residue Cys158 of recombinant apoobelin was substituted for sera ine (C158S, S-mutant) or alanine (C158A, A-mutant). These point mutations resulted in significant changes in the apoobelin structure accompanied by slowing of photoprotein complex formation, decrease of its stability, and changing of its bioluminescence characteristics. The enzymatic properties of the photoprotein decreased in the series: wild-type protein > S-mutant > A-mutant. This is consistent with rank of nucleophilicity SH > OH > CH3 of cysteine, serine, and alanine side chain functional groups, respectively. Possible mechanisms of the involvement of the apoobelin Cys158 SH-group in the formation of the enzyme-substrate complex are considered.

Аннотация: Obelin mRNA obtained in vitro with the aid of SP6 RNA polymerase was translated in a wheat germ cell-free system, Only the polypeptide with a molecular mass of about 20 kDa was synthesized. The activation of apoobelin with a synthetic coelenterazine revealed a luminescence activity initiated by calcium. The specific activity was 3.6 +/- 0.4 x 10(15) photons per mg of the in vitro synthesized obelin (k = 6.9 s(-1)). The luminescence of the obelin was in a good correlation with the protein concentration calculated by the incorporation of [C-14]Leu. The determination of the amount of de novo synthesized obelin based on measurement of its luminescence is one-thousand times more sensitive than the approach based on the incorporation of labeled amino acid. Thus, obelin mRNA has some advantages for evaluating the efficiency of cell-free translation when compared with standard methods. (C) 1995 Academic Press, Inc.

Аннотация: The bright bioluminescence of copepod Metridia longa is conditioned by a small secreted coelenterazinedependent luciferase (MLuc). To date, three isoforms of MLuc differing in length, sequences, and some properties were cloned and successfully applied as high sensitive bioluminescent reporters. In this work, we report cloning of a novel group of genes from M. longa encoding extremely psychrophilic isoforms of MLuc (MLuc2-type). The novel isoforms share only similar to 54-64% of protein sequence identity with the previously cloned isoforms and, consequently, are the product of a separate group of paralogous genes. The MLuc2 isoform with consensus sequence was produced as a natively folded protein using baculovirus/ insect cell expression system, purified, and characterized. The MLuc2 displays a very high bioluminescent activity and high thermostability similar to those of the previously characterized M. longa luciferase isoform MLuc7. However, in contrast to MLuc7 revealing the highest activity at 12-17 degrees C and 0.5 M NaCl, the bioluminescence optima of MLuc2 isoforms are at similar to 5 degrees C and 1 M NaCl. The MLuc(2) adaptation to cold is also accompanied by decrease of melting temperature and affinity to substrate suggesting a more conformational flexibility of a protein structure. The luciferase isoforms with different temperature optima may provide adaptability of the M. longa bioluminescence to the changes of water temperature during diurnal vertical migrations.

Mitrocomin from the jellyfish Mitrocoma cellularia with deleted C-terminal tyrosine reveals a higher bioluminescence activity compared to wild type photoprotein / L. P. Burakova [et al.] // J. Photochem. Photobiol. B Biol. - 2016. - Vol. 162. - P286-297, DOI 10.1016/j.jphotobiol.2016.06.054 . - ISSN 1011-1344
Аннотация: The full-length cDNA genes encoding five new isoforms of Ca2 +-regulated photoprotein mitrocomin from a small tissue sample of the outer bell margin containing photocytes of only one specimen of the luminous jellyfish Mitrocoma cellularia were cloned, sequenced, and characterized after their expression in Escherichia coli and subsequent purification. The analysis of cDNA nucleotide sequences encoding mitrocomin isoforms allowed suggestion that two isoforms might be the products of two allelic genes differing in one amino acid residue (64R/Q) whereas other isotypes appear as a result of transcriptional mutations. In addition, the crystal structure of mitrocomin was determined at 1.30 A resolution which expectedly revealed a high similarity with the structures of other hydromedusan photoproteins. Although mitrocomin isoforms reveal a high degree of identity of amino acid sequences, they vary in specific bioluminescence activities. At that, all isotypes displayed the identical bioluminescence spectra (473–474 nm with no shoulder at 400 nm). Fluorescence spectra of Ca2 +-discharged mitrocomins were almost identical to their light emission spectra similar to the case of Ca2 +-discharged aequorin, but different from Ca2 +-discharged obelins and clytin which fluorescence is red-shifted by 25–30 nm from bioluminescence spectra. The main distinction of mitrocomin from other hydromedusan photoproteins is an additional Tyr at the C-terminus. Using site-directed mutagenesis, we showed that this Tyr is not important for bioluminescence because its deletion even increases specific activity and efficiency of apo-mitrocomin conversion into active photoprotein, in contrast to C-terminal Pro of other photoproteins. Since genes in a population generally exist as different isoforms, it makes us anticipate the cloning of even more isoforms of mitrocomin and other hydromedusan photoproteins with different bioluminescence properties. © 2016 Elsevier B.V.

Shining Light on the Secreted Luciferases of Marine Copepods: Current Knowledge and Applications. / S. V. Markova, M. D. Larionova, E. S. Vysotski // Photochemistry and photobiology. - 2018, DOI 10.1111/php.13077 . - ISSN 1751-1097
Аннотация: Copepod luciferases - a family of small secretory proteins of 18.4-24.3 kDa, including a signal peptide, are responsible for bright secreted bioluminescence of some marine copepods. The copepod luciferases use coelenterazine as a substrate to produce blue light in a simple oxidation reaction without any additional cofactors. They do not share sequence or structural similarity with other identified bioluminescent proteins including coelenterazine-dependent Renilla and Oplophorus luciferases. The small size, strong luminescence activity and high stability, including thermostability, make secreted copepod luciferases very attractive candidates as reporter proteins which are particularly useful for nondisruptive reporter assays and for high-throughput format. The most known and extensively investigated representatives of this family are the first cloned GpLuc and MLuc luciferases from copepods Gaussia princeps and Metridia longa, respectively. Immediately after cloning these homologous luciferases were successfully applied as bioluminescent reporters in vivo and in vitro, and since then the scope of their applications continues to grow. This review is an attempt to systemize and critically evaluate the data scattered through numerous articles regarding the main structural features of copepod luciferases, their luminescent and physicochemical properties. We also review the main trends of their application as bioluminescent reporters in cell and molecular biology. This article is protected by copyright. All rights reserved.

Аннотация: Bioluminescent proteins are widely used as reporter molecules in various in vitro and in vivo assays. The smallest isoform of Metridia luciferase (MLuc7) is a highly active, naturally secreted enzyme which, along with other luciferase isoforms, is responsible for the bright bioluminescence of marine copepod Metridia longa. In this study, we report the construction of two variants of a hybrid protein consisting of MLuc7 and 14D5a single-chain antibody to the surface glycoprotein E of tick-borne encephalitis virus as a model fusion partner. We demonstrate that, whereas fusion of a single-chain antibody to either N-or C-terminus of MLuc7 does not affect its bioluminescence properties, the binding site on the single-chain antibody influences its binding capacity. The affinity of 14D5a-MLuc7 hybrid protein (KD = 36.2 nM) where the C-terminus of the single-chain antibody was fused to the N-terminus of MLuc7, appeared to be 2.5-fold higher than that of the reverse, MLuc7-14D5a (KD = 87.6 nM). The detection limit of 14D5a-MLuc7 hybrid protein was estimated to be 45 pg of the recombinant glycoprotein E. Although the smallest isoform of M. longa luciferase was tested as a fusion partner only with a single-chain antibody, it is reasonable to suppose that MLuc7 can also be successfully used as a partner for genetic fusion with other proteins. © 2020 by the authors.

Аннотация: Bright bioluminescence of ctenophores is conditioned by Ca2+-regulated photoproteins. Although they share many properties characteristic of hydromedusan Ca2+-regulated photoproteins responsible for light emission of marine animals belonging to phylum Cnidaria, a substantial distinction still exists. The ctenophore photoproteins appeared to be extremely sensitive to light—they lose the ability for bioluminescence on exposure to light over the entire absorption spectrum. Inactivation is irreversible because keeping the inactivated photoprotein in the dark does not recover its activity. The capability to emit light can be restored only by incubation of inactivated photoprotein with coelenterazine in the dark at alkaline pH in the presence of oxygen. Although these photoproteins were discovered many years ago, only the cloning of cDNAs encoding these unique bioluminescent proteins in the early 2000s has provided a new impetus for their studies. To date, cDNAs encoding Ca2+-regulated photoproteins from four different species of luminous ctenophores have been cloned. The amino acid sequences of ctenophore photoproteins turned out to completely differ from those of hydromedusan photoproteins (identity less than 29%) though also similar to them having three EF-hand Ca2+-binding sites. At the same time, these photoproteins reveal the same two-domain scaffold characteristic of hydromedusan photoproteins. This review is an attempt to systemize and critically evaluate the data scattered through various articles regarding the structural features of recombinant light-sensitive Ca2+-regulated photoproteins of ctenophores and their bioluminescent and physicochemical properties as well as to compare them with those of hydromedusan photoproteins. In addition, we also discuss the prospects of their biotechnology applications. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.

Аннотация: Translation of apoobelin mRNA in a cell-free wheat germ translation system in the presence of coelenterazine and molecular oxygen results in cotranslational formation of active photoprotein. Active obelin formation is recorded by its luminescence, either direct in the translation mixture in the presence of coelenterazine and calcium ions or in aliquots from the translation mixture. In the second case translation is carried out with coelenterazine and EGTA. Registration of the translation course by luminescence of the synthesized product in both cases allows use of apoobelin mRNA at very low concentrations as an internal marker for immediate measure of protein biosynthesis activity of in vitro translation systems. It is shown that the simultaneous translation of any other mRNA does not affect translation of photoprotein mRNAs under standard conditions. Continuous registration of luminescence in a cuvette of a liquid scintillation counter in photon-counting mode varies the time of signal accumulation in a wide temporal range, thus increasing the numerical values of the recorded signals. Registration of photoprotein luminescence during translation can be used to obtain additional information about the translation process, for example codon reading speed, about protein folding, and about the formation of active proteins on ribosomes.

Аннотация: A model for the spatial structure of firefly luciferase-ATP-luciferin complex is suggested using the coordinates of unliganded luciferase and the enzyme-substrate complex of the adenylating subunit of gramicidin S synthetase known from the literature. Conformational changes in luciferase can occur during substrate binding resulting in a relative orientation of two luciferase domains similar to that in case of the AMP-phenylalanine-synthetase complex. The model is consistent with data on the physicochemical properties of firefly luciferase and its complexes with the substrates.

Аннотация: Quick response to different impacts and easy measurement make the luminescent systems of luminous bacteria an object convenient for application in various fields. Cloning of gene luminescence in different organisms is currently used to study both the survival of microbial cells and the effect of different factors on their metabolic activity, including the environment. A primary test-object in estimating bacteriological contamination of water bodies, Escherichia coli, can be conveniently used as an indicator of bactericidal properties of aquatic ecosystems. The application of Escherichia coli Z905/pPHL7 (lux(+)) as a marker microorganism can facilitate monitoring the microbiological status of closed biocenoses, including systems with higher organisms. The investigation of various parameters of microecosystems (carbon nutrition type, concentrations of inorganic ions and toxic compounds) shows that the recombinant strain E. coli Z905/pPHL7 can be effectively used as a marker.

Аннотация: Coelenterazine-dependent copepod luciferases containing natural signal peptide for secretion are a very convenient analytical tool as they enable monitoring of intracellular events with high sensitivity, without destroying cells or tissues. This property is well suited for application in biomedical research and development of cell-based assays for high throughput screening. We report the cloning of cDNA gene encoding a novel secreted non-allelic 16.5-kDa isoform (MLuc7) of Metridia longa luciferase, which, in fact, is the smallest natural luciferase of known for today. Despite the small size, isoform contains 10 conservative Cys residues suggesting the presence of up to 5 S-S bonds. This hampers the efficient production of functionally active recombinant luciferase in bacterial expression systems. With the use of the baculovirus expression system, we produced substantial amounts of the proper folded MLuc7 luciferase with a yield of similar to 3 mg/L of a high purity protein. We demonstrate that MLuc7 produced in insect cells is highly active and extremely thermostable, and is well suited as a secreted reporter when expressed in mammalian cells ensuring higher sensitivity of detection as compared to another Metridia luciferase isoform (MLuc164) which is widely employed in real-time imaging.

Аннотация: The dynamics of accumulation of polyhydroxybutyrate (PHB) and the activities of key enzymes of PHB metabolism (beta-ketothiolase, acetoacetyl-CoA reductase, PHB synthase, D-hydroxybutyrate dehydrogenase, and PHB depolymerase) in the hydrogen bacterium Ralstonia eutropha B5786 were studied under various conditions of carbon nutrition and substrate availability. The highest activities of beta-ketothiolase, acetoacetyl-CoA reductase, and PHB synthase were recorded during acceleration of PHB synthesis. The activities of enzymes catalyzing PHB depolymerization (PHB depolymerase and D-hydroxybutyrate dehydrogenase) were low, being expressed only upon stimulated endogenous PHB degradation. The change of carbon source (CO2 or fructose) did not affect the time course of the enzyme activity significantly.
