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.

The smallest isoform of Metridia longa luciferase as a fusion partner for hybrid proteins / M. D. Larionova, S. V. Markova, N. V. Tikunova, E. S. Vysotski // Int. J. Mol. Sci. - 2020. - Vol. 21, Is. 14. - Ст. 4971. - P1-16, DOI 10.3390/ijms21144971 . - ISSN 1661-6596

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: The gene of the hybrid protein that encodes the double synthetic fragment proZZ of the immunoglobulin-binding domain of protein A of Staphylococcus aureus and apo-obelin joined by a short linker has been cloned. The corresponding hybrid protein has been obtained by expression in Escherichia coli cells. The protein activated with a substrate (coelenterazine) possesses the bioluminescent Ca2+-dependent activity of the photoprotein close to that of recombinant wild-type obelin, and the immunoglobulin-binding ability of protein A. It has been shown that the hybrid can be used as a highly sensitive label to detect antibodies and estimate their affinity and interaction with recombinant proteins, as well as in investigations of other kinds.

Аннотация: This paper is devoted to the comparative stude of redundancy of genetic texts of various organisms and viruses. To determine the tedundance of a gene, we have introduced the strict measure for that latter. The measure for a text's redundance is the length of restriction of Frequence/Correlation Dictionary of a given genetic text. Frequence/Correlation Dictionary is the ser of all subsequences belang to a given genetic text, accompanied by the frequencies of their occurrence. The restriction length is defined as that one, for which all the subsequences (of that length) are unique. We have found, that genes of human viruses are less redundant, in comparison to those of human genes. Other aspects of a comparative redundance invastigations of the genes are discussed. The problem of the determination of truet intron could be treated by this methodology, as well, as the evolution of genome.

The Center of Origin and Colonization Routes of Noble Salmons of the Genus Salmo (Salmonidae, Actinopterigii) / V. S. Artamonova, S. A. Afanasyev, N. V. Bardukov [et al.] // Doklad. Biochem. Biophys. - 2020. - Vol. 493, Is. 1. - P171-177, DOI 10.1134/S160767292004002X . - ISSN 1607-6729

Аннотация: Abstract: Genetic diversity and colonization routes of noble salmons were studied using a partial nucleotide sequence of the mitochondrial COI gene. The brown trout S. trutta, which is the most ancient species of the genus, was concluded to originate from the modern southeastern Pontic-Caspian area, which is currently inhabited by members of the subspecies S. trutta oxianus. Migrating westward while the Paratethys was in existence (5–34 million years ago), species of the genus colonized ancient water bodies in the modern Mediterranean basin and formed many isolated populations that survived desiccation of the Mediterranean Sea (5–6 million years ago). The Strait of Gibraltar mediated brown trout migrations to Northern Europe; the subspecies S. trutta trutta belongs to a relatively young phylogenetic lineage of the species. A separate brown trout lineage, currently classified as the subspecies S. trutta labrax, formed most likely in the area of the modern Danube basin, which was a relatively separate part of the Paratethys and was sometimes isolated as the Pannonian Lake. A highly divergent phylogenetic lineage of Atlantic salmon (S. salar) haplotypes originates from a haplotype of the brown trout that inhabited the area of the modern Strait of Gibraltar. © 2020, Pleiades Publishing, Ltd.

Аннотация: Background: Canine parvovirus (CPV) is now recognized as a serious threat to the dog breeding industry worldwide. Currently used CPV vaccines all have their specific drawbacks, prompting a search for alternative safe and effective vaccination strategies such as subunit vaccine. VP2 protein is the major antigen targeted for developing CPV subunit vaccine, however, its production in baculovirus expression system remains challenging due to the insufficient yield. Therefore, our study aims to increase the VP2 protein production by using an improved baculovirus expression system and to evaluate the immunogenicity of the purified VP2 protein in mice. Results: The results showed that high-level expression of the full length VP2 protein was achieved using our modified baculovirus expression system. The recombinant virus carrying two copies of VP2 gene showed the highest expression level, with a productivity of 186 mg/L, which is about 1.4-1.6 fold that of the recombinant viruses carrying only one copy. The purified protein reacted with Mouse anti-His tag monoclonal antibody and Rabbit anti-VP2 polyclonal antibody. BALB/c mice were intramuscularly immunized with purified VP2 protein twice at 2 week intervals. After vaccination, VP2 protein could induce the mice produce high level of hemagglutination inhibition antibodies. Conclusions: Full length CPV VP2 protein was expressed at high level and purified efficiently. Moreover, it stimulated mice to produce high level of antibodies with hemmaglutination inhibition properties. The VP2 protein expressed in this study could be used as a putative economic and efficient subunit vaccine against CPV infection. © 2020 The Author(s).

Аннотация: The structure and functional activity of microbial complexes of a forest oligo-mesotrophic subshrub- grass-moss bog (OMB, Central Evenkiya) and a subshrub-sedge bog in the polygonal tundra (PB, Lena River Delta Samoylovsky Island) was studied. Soil of the forest bog (OMB) differed from that of the polygonal tundra bog (PB) in higher productivity (Corg, Ntotal, P, and K reserves), higher biomass of aerobic chemoorganotrophs (2.0 to 2.6 times), and twice the level of available organic matter. The contribution of microorganisms to the carbon pool was different, with the share of Cmic in Corg 1.4 to 2.5 times higher in PB compared to OMB. Qualitative composition of the methane cycle microorganisms in PB and OMB soils differed significantly. Methanogenic archaea (Euryarchaeota) in the shrub-sedge PB of tundra were more numerous and diverse than in the oligo-mesotrophic bog (OMB) and belonged to six families (Methanomassiliicoccaceae, Methanoregulaceae, Methanobacteriaceae, Methanomicrobiaceaee, Methanosarcinaceae, and Methanotrichaceae), while members of only four families (Methanosarcinacea, Methanobacteriaceae, Methanotrichaceae, and Methanomassiliicoccaceae) were revealed in OMB. In both bogs, methane-oxidizing bacteria belonged to Alphaproteobacteria (II) and Gammaproteobacteria (I). Methanotroph diversity was higher in OMB than in PB. Microbial communities of PB soils had higher potential activity of methanogenesis and methanotrophy compared to those of OMB. Methanogenic and methanotrophic activities in PB were 20 and 2.3 times higher, respectively, than in OMB. © 2018, Pleiades Publishing, Ltd.

Аннотация: The biodiversity of bacterial communities along the Yenisei River at section c. 1800 km was studied using next-generation sequencing of 16S rRNA genes and common biodiversity indices. Overall, 3022 unique operational taxonomic units were identified. Actinobacteria and Proteobacteria were the dominant phyla at all sampling sites. The highest alpha-diversity values were found in the middle section of the studied river. The beta-diversity of bacterial assemblages in the river was related to the surrounding landscape (biome): three distinctly different bacterial assemblages occurred in sections of the river, situated in mountain taiga, plain taiga and in a region of permafrost, covered by forest-tundra and tundra. Tributaries arising from these different landscapes likely contributed substantially to the variations of Yenisei bacterial communities. In contrast to a prediction of the river continuum concept, the proportion of photoautotrophic Cyanobacteria in bacterial assemblages did not increase downstream, but peaked at the middle section. © 2014 Federation of European Microbiological Societies.

Аннотация: Meromictic lakes usually harbour certain prevailing anoxygenic phototrophic bacteria in their anoxic zone, such as the purple sulfur bacterium (PSB) Thiocapsa sp. LSW (hereafter LSW) in Lake Shunet, Siberia. PSBs have been suggested to play a vital role in carbon, nitrogen and sulfur cycling at the oxic–anoxic interface of stratified lakes; however, the ecological significance of PSBs in the lake remains poorly understood. In this study, we explored the potential ecological role of LSW using a deep-sequencing analysis of single-cell genomics associated with flow cytometry. An approximately 2.7 Mb draft genome was obtained based on the co-assembly of five single-cell genomes. LSW might grow photolithoautotrophically and could play putative roles not only as a carbon fixer and diazotroph, but also as a sulfate reducer/oxidizer in the lake. This study provides insights into the potential ecological role of Thiocapsa sp. in meromictic lakes. © 2021 The Authors.

Аннотация: Multiplex simultaneous genotyping technique was developed for four polymorphisms in genes coding for blood coagulation factors and homocysteine metabolism which are considered as thrombophilia related mutations: FV Leiden, FII G20210A, MTHFR C677T, and FVII G10976A. It is based on primer extension reaction with the following bioluminescent solid-phase microassay. At that, two different in bioluminescence obelin mutants were applied to simultaneous detection of two gene allelic variants. The assay is carried out in microtiter plate format and provides fast and reliable genotyping of four single nucleotide polymorphisms in four different genes within 2.5 hours. A large number of clinical samples were analyzed and the obtained results were found to be in complete correlation with those obtained by using conventional RT-PCR techniques. © 2015 Bentham Science Publishers.

Аннотация: A cDNA clone encoding the Ca2+-activated photoprotein, obelin (Obl), from Obelia longissima was sequenced. The nucleotide (nt) sequence contained two long overlapping open reading frames (ORFs), one of which encoded apoobelin (apoObl). The deduced amino acid (aa) sequence of apoObl revealed that this 195-aa protein has three EF-hand structures that are characteristic for Ca2+-binding domains. Strong aa homology was shown among apoObl, apoaequorin and apoclytin. The second ORF present in the obl cDNA consists of 139 codons and encodes a very basic protein with a calculated pI of 10.56 and a molecular mass of 16153 Da.

GENE -- CORRELATION -- REDUNDANCY
Аннотация: A new method is proposed for measuring and comparing the redundancy of genetic texts. It is based on compiling for a given text a frequency/correlation dictionary encompassing all the words (subsequences) of length from 1 to N encountered in the text (N is text length); the measure of redundancy is the minimal length at which all words are unique. Preliminary results are reported for different genetic texts.

Аннотация: The article is devoted to analysis of the internal gene structure with respect to redundancy of exons and introns. Human genes with precisely determined exon-intron structure were studied. Redundancy of each exon and intron within a certain gene was measured. In the analyzed human genes, introns were more redundant than exons. Redundancy was determined as the minimal length of a word (oligonucleotide) that is present as a single copy within the nucleotide sequence studied. Mechanisms are discussed that lead to disturbances in the relationships found between the redundancies of exons and introns.

Properties of recombinant fluorescent proteins from Photobacterium leiognathi and their interaction with luciferase intermediates / V. N. Petushkov, B. G. Gibson, J. Lee // Biochemistry. - 1995. - Vol. 34, Is. 10. - P3300-3309 . - ISSN 0006-2960

Аннотация: Ligand binding and luciferase interaction properties of the recombinant protein corresponding to the lumazine protein gene (EMBL X56534) of Photobacterium leiognathi have been determined by fluorescence dynamics, circular dichroism, gel filtration, and SDS-PAGE. Scatchard analysis of a fluorescence titration shows that the apoprotein possess one binding site, and at 30В°C the KdS (?M) are as follows: 6,7-dimethyl-8-ribityllumazine, 0.26; riboflavin, 0.53; and much more weakly bound FMN, 30. All holoproteins are highly fluorescent and have absorption spectra distinct from each other and from the free ligands. The longest wavelength absorption maxima are, respectively (nm, 2В°C), 420,463, and 458. Ligand binding produces no change in the far-UV circular dichroism; all have mean residual ellipticity at 210 nm of -6500 deg cm2 dmol-1, the same as the native protein. However, in the bioluminescence reaction only the lumazine holoprotein shows a bioluminescence effect. Fluorescence emission anisotropy decay was used to establish that none of these holoproteins complexed with native luciferase and that the lumazine protein alone formed a 1:1 complex with the luciferase hydroxyflavin fluorescent transient and the luciferase peroxyflavin intermediates, revealed by a dominant channel of anisotropy loss, with rotational correlation time of 2.5 ns, and attributed to excitation transfer from the luciferase flavin donor to the acceptor, the lumazine ligand. The complex stability was sufficient to allow its isolation by FPLC gel filtration and verification by SDS-PAGE. These methods also confirmed the absence of interaction of the holoflavoproteins.
