Abstract
Mitochondrial ribosome assembly is a complex multi-step process involving many additional factors. Ribosome formation differs in various groups of organisms. However, there are universal steps of assembly and conservative factors that have been retained in evolutionarily distant taxa. METTL17, the object of the current study, is one of these conservative factors involved in mitochondrial ribosome assembly. It is present in both bacteria and the mitochondria of eukaryotes, in particular mice and humans. In this study, we tested a hypothesis of putative METTL17 methyltransferase activity. MALDI-TOF mass spectrometry was used to evaluate the methylation of a putative METTL17 target - a 12S rRNA region interacting with METTL17 during mitochondrial ribosome assembly. The investigation of METTL17 and other mitochondrial ribosome assembly factors is of both fundamental and practical significance, because defects in mitochondrial ribosome assembly are often associated with human mitochondrial diseases.

Abstract
Mitochondrial diseases (MDs) associated with nuclear gene mutations are part of a large group of inherited diseases caused by the suppression of energy metabolism. These diseases are of particular interest, because nuclear genes encode not only most of the structural proteins of the oxidative phosphorylation system (OXPHOS), but also all the proteins involved in the OXPHOS protein import from the cytoplasm and their assembly in mitochondria. Defects in any of these proteins can lead to functional impairment of the respiratory chain, including dysfunction of complex I that plays a central role in cellular respiration and oxidative phosphorylation, which is the most common cause of mitopathologies. Mitochondrial diseases are characterized by an early age of onset and a progressive course and affect primarily energy-consuming tissues and organs. The treatment of MDs should be initiated as soon as possible, but the diagnosis of mitopathologies is extremely difficult because of their heterogeneity and overlapping clinical features. The molecular pathogenesis of mitochondrial diseases is investigated using animal models: i.e. animals carrying mutations causing MD symptoms in humans. The use of mutant animal models opens new opportunities in the study of genes encoding mitochondrial proteins, as well as the molecular mechanisms of mitopathology development, which is necessary for improving diagnosis and developing approaches to drug therapy. In this review, we present the most recent information on mitochondrial diseases associated with nuclear gene mutations and animal models developed to investigate them.

Abstract
We studied the state of the DNA repair system and apoptosis in young mice carrying heterozygous inactivating mutation in the NBS1 gene (c.1971insT, p.Arg658Stop). In the peripheral blood cells of 4-month-old NBS1insT males, the %DNA in the comet tail was higher by 10% than in wild-type mice (wt) (p<0.05). In hepatocytes of NBS1insT mice, the proportion of γH2AX+ nuclear regions marking DNA double-strand breaks was lower by 2 times than in wt mice (p<0.05), which can be an indicator of less efficient DNA repair. In the kidney tissue of NBS1insT mice, a tendency towards the proapoptotic ratio of Bax and Bcl-2 protein markers was revealed against the background of their reduced expression. Thus, the disturbances detected NBS1insT mice in young age suggest that this model is promising for further studies of carcinogenesis.

Abstract
The Flow-seq method is based on using reporter construct libraries, where a certain element regulating the gene expression of fluorescent reporter proteins is represented in many thousands of variants. Reporter construct libraries are introduced into cells, sorted according to their fluorescence level, and then subjected to next-generation sequencing. Therefore, it turns out to be possible to identify patterns that determine the expression efficiency, based on tens and hundreds of thousands of reporter constructs in one experiment. This method has become common in evaluating the efficiency of protein synthesis simultaneously by multiple mRNA variants. However, its potential is not confined to this area. In the presented review, a comparative analysis of the Flow-seq method and other alternative approaches used for translation efficiency evaluation of mRNA was carried out; the features of its application and the results obtained by Flow-seq were also considered.

Abstract
Searching for novel compounds with antibiotic activity and understanding their
mechanism of action is extremely important. The ribosome is one of the main
targets for antibiotics in bacterial cells. Even if the molecule does not suit
the clinical application for whatever reasons, an investigation of its
mechanism of action can deepen our understanding of the ribosome function. Such
data can inform us on how the already used translational inhibitors can be
modified. In this study, we demonstrate that 1-(2-oxo-2-((4-phenoxyphenyl)

Abstract
Methyltransferases (MTases) play an important role in the functioning of living systems, catalyzing the methylation reactions of DNA, RNA, proteins, and small molecules, including endogenous compounds and drugs. Many human diseases are associated with disturbances in the functioning of these enzymes; therefore, the study of MTases is an urgent and important task. Most MTases use the cofactor S‑adenosyl‑L‑methionine (SAM) as a methyl group donor. SAM analogs are widely applicable in the study of MTases: they are used in studies of the catalytic activity of these enzymes, in identification of substrates of new MTases, and for modification of the substrates or substrate linking to MTases. In this review, new synthetic analogs of SAM and the problems that can be solved with their usage are discussed.

Abstract
For the search of anticancer compounds in modern large chemical libraries, new approaches are of great importance. Cocultivation of the cells of tumor and non-tumor etiology may reveal specific action of chemicals on cancer cells and also take into account some effects of the tumor cell's microenvironment. The fluorescent cell cocultivation test (FCCT) has been developed for screening of substances that are selectively cytotoxic on cancerous cells. It is based on the mixed culture of lung carcinoma cells A549'_EGFP and noncancerous fibroblasts of lung VA13_Kat, expressing different fluorescent proteins. Analysis of the cells was performed with the high-resolution scanner to increase the detection rate. The combination of cocultivation of cells with scanning of fluorescence reduces the experimental protocol to three steps: cells seeding, addition of the substance, and signal detection. The FCCT analysis does not disturb the cells and is compatible with other cell-targeted assays. The suggested method has been adapted for a high-throughput format and applied for screening of 2,491 compounds. Three compounds were revealed to be reproducibly selective in the FCCT although they were invisible in cytotoxicity tests in individual lines. Six structurally diverse indole, coumarin, sulfonylthiazol, and rifampicin derivatives were found and confirmed with an independent assay (MTT) to be selectively cytotoxic to cancer cells in the studied model.

Abstract
Mitochondria are energy producing organelles of the eukaryotic cell, involved in the synthesis of key metabolites, calcium homeostasis and apoptosis. Protein biosynthesis in these organelles is a relic of its endosymbiotic origin. While mitochondrial translational factors have homologues among prokaryotes, they possess a number of unique traits. Remarkably as many as four mammalian mitochondrial proteins possess a clear similarity with translation termination factors. The review focuses on the ICT1, which combines several functions. It is a non-canonical termination factor for protein biosynthesis, a rescue factor for stalled mitochondrial ribosomes, a structural protein and a regulator of proliferation, cell cycle, and apoptosis. Such a diversity of roles demonstrates the high functionality of mitochondrial translation associated proteins and their relationship with numerous processes occurring in a living cell.

Abstract
Methylation of nucleotides in rRNA is one of the basic mechanisms of bacterial resistance to protein synthesis inhibitors. The genes for corresponding methyltransferases have been found in producer strains and clinical isolates of pathogenic bacteria. In some cases, rRNA methylation by housekeeping enzymes is, on the contrary, required for the action of antibiotics. The effects of rRNA modifications associated with antibiotic efficacy may be cooperative or mutually exclusive. Evolutionary relationships between the systems of rRNA modification by housekeeping enzymes and antibiotic resistance-related methyltransferases are of particular interest. In this review, we discuss the above topics in detail.

Abstract
Ribosome stalling during translation significantly reduces cell viability, because cells have to spend resources on the synthesis of new ribosomes. Therefore, all bacteria have developed various mechanisms of ribosome rescue. Usually, the release of ribosomes is preceded by hydrolysis of the tRNA-peptide bond, but, in some cases, the ribosome can continue translation thanks to the activity of certain factors. This review describes the mechanisms of ribosome rescue thanks to trans-translation and the activity of the ArfA, ArfB, BrfA, ArfT, HflX, and RqcP/H factors, as well as continuation of translation via the action of EF-P, EF-4, and EttA. Despite the ability of some systems to duplicate each other, most of them have their unique functional role, related to the quality control of bacterial translation in certain abnormalities caused by mutations, stress cultivation conditions, or antibiotics.

Abstract
Somatic Cell Nuclear Transfer (SCNT) technique was used to produce the first viable cloned cattle offspring in Russia. Whole-genome SNP genotyping confirmed that the cloned calf was identical to the fibroblast cell line that was used for SCNT. CRISPR/Cas9 approach was subsequently used to knock out genes for beta-lactoglobulin gene (PAEP) and the beta-lactoglobulin-like protein gene (LOC100848610) in the fibroblast cells. Gene editing (GE) efficiency was 4.4% for each of these genes. We successfully obtained single-cell-derived fibroblast colonies containing PAEP and LOC100848610 knockouts, which will be used to produce beta-lactoglobulin-deficient cattle.

Abstract
The generation of transgenic model organisms (primarily mice) is an integral part of modern fundamental and applied research. Simple techniques based on the biology of these laboratory rodents can often increase efficiency when generating genome-edited mouse strains. In this study, we share our three years of experience in the optimization of mouse genome editing based on microinjection of CRISPR/Cas9 components into ca. 10,000 zygotes. We tested a number of techniques meant to improve efficiency in generating knockout mice, such as optimization of the superovulation method and choosing the optimal mouse strains to be used as zygote donors and foster mothers. The presented results might be useful to laboratories aiming to quickly and efficiently create new mouse strains with tailored genome editing.

Abstract
TRM112 is necessary for the activation and stability of several methyltransferases involved in the modification of various components of the translation apparatus. This unique protein is a partner for enzymes that methylate tRNA, rRNA, and the translation termination factor. Here we review the structural and functional features of the TRM112 complexes with methyltransferases and provide, where possible, information on their significance.

Abstract
Proteins containing the NIF3 domain are highly conserved and are found in bacteria, eukaryotes, and archaea. YbgI is an Escherichia coli protein whose gene is conserved among bacteria. The structure of YbgI is known; however, the function of this protein in cells remains obscure. Our studies of E. coli cells with deleted ybgI gene suggest that YbgI is involved in formation of the bacterial cell wall.

Abstract
The flagellum of a bacterium is a supramolecular structure of extreme complexity comprising simultaneously both a unique system of protein transport and a molecular machine that enables the bacterial cell movement. The cascade of expression of genes encoding flagellar components is closely coordinated with the steps of molecular machine assembly, constituting an amazing regulatory system. Data on structure, assembly, and regulation of flagellar gene expression are summarized in this review. The regulatory mechanisms and correlation of the process of regulation of gene expression and flagellum assembly known from the literature are described.

Abstract
Antibacterial compounds are one of the essential classes of clinically important drugs. High throughput screening allowed revealing potential antibiotics active towards any molecular target in bacterial cell. We used a library of 9820 organic compounds with highly diversified structures to screen for antibacterial activity. As the result of automated screening, 103 compounds were found to possess antibacterial activity against Escherichia coli. The properties of these compounds were compared with those of initial library. Non-linear Kohonen mapping was used to analyze the differences between non-active molecules from initial library, identified antibacterial hits and compounds with reported antibacterial activity. It was found that identified antibacterial compounds are located in the separated area of chemical space. It can be therefore suggested that these molecules belong to novel classes of antibacterial compounds and could be studied further.

Abstract
Genomewide mapping of posttranscriptional modification in eukaryotic RNA allowed to reveal tens of thousands modification sites. Among modified nucleotides of eukaryotic RNA 6-methyladenosine, 5-methylcytidine, pseudouridine, inosine, and others. Many modification sites are conserved, many are regulated. Function is known for a small subset of modified nucleotides, while the role of majority of them is still obscure. Global character of mRNA modifications allowed scientists to coin a new term, RNA epigenetics. The review is about posttranscriptional messenger RNA modifications in eukaryotes. Main modifications, their role in cell, their mapping techniques and proteins, that are responsible for such RNA modifications are observed.

Abstract
A ribosome is a ribonucleoprotein that performs the synthesis of proteins. Ribosomal RNA of all organisms includes a number of modified nucleotides, such as base or ribose methylated and pseudouridines. Methylated nucleotides are highly conserved in bacteria and some even universally. In this review we discuss available data on a set of modification sites in the most studied bacteria, Escherichia coli. While most rRNA modification enzymes are known for this organism, the function of the modified nucleotides is rarely identified.

Abstract
Ribosome is a macromolecular complex, which is responsible for protein biosynthesis. Two bacterial ribosomal subunits contain more than 4000 RNA nucleotides and 50 proteins. Ribosome assembly is a complicated multi-step process, vitally important for cell. In this review we summarised present-day conceptions about the mechanism of the bacterial ribosome assembly in the cell and in vitro model systems. Some details of the assembly of this machinery are still-unknown.

Abstract
In this work we describe methodology for studying the role of bacterial ribosome modification in the regulation of gene expression. Ribosomal components modification influences translation efficiencies of certain mRNAs. Proteome analysis allows us to identify cellular protein composition change caused by ribosome modification gene knockout. Particular stage of gene expression responsible for certain protein concentration change could be found using reporter constructs. After identification of mRNA species, whose translation is influenced by ribosome modification we can determine exact mRNA region responsible for the observed changes. The developed methodology can be applied for studying other translational control mechanisms.

Abstract
The non-canonical base-pair C2475/G2529 joins helices 89 and 91 of the 23S rRNA in the large subunit of E. coli ribosomes. These nucleotides are located at the "crossroads" between the peptidyl transferase center, the sarcin-ricin loop and the GTPase-associated center. We probed the functional role of nucleotides C2475/G2529 by the mutations C2475G, C2475G/G2529C and deltaA2471/U2479 of 23S rRNA. All these mutations had no influence on the elongation factors activity but had different effects on the cell growth, 23S rRNA conformation and translation initiation. C2475G/G2529C and C2475G mutations led to more or less substantial decrease in IF2.GDPNP binding to the ribosomes, and IF2-assisted initiation complex formation. Ribosome-dependent GTPase activity of IF2 was enhanced by both C2475G/G2529C and C2475G mutations. Mutation deltaA2471/U2479 has no influence on IF2.GDPNP binding to the ribosome, but reduces IF2-dependent formation of initiation complex and the ribosome-dependent GTPase activity. Thus, the contact between helices 89 and 91 is important for efficient IF2 functioning in translation initiation.

Abstract
We studied the behavior of the signal recognition particle (SRP) components in Saccharomyces cerevisiae upon deficiencies of the protein transport caused by the absence of the SRP membrane receptor alpha-subunit. A decrease in the concentration of the SRP membrane receptor alpha-subunit in the cell significantly decreased the level of an SRP component, protein SRP72, as well as the levels of mRNAs of SRP protein components and the SRP receptor beta-subunit. But the amount of 7SL RNA remained unchanged. In contrast, in Escherichia coli cells the gradual decrease in the level of the protein FtsY (a homolog of the SRP membrane receptor alpha-subunit) was not associated with changes in the Ffh protein level.

Abstract
The plenty of data about structural changes in the ribosome during its functioning has been accumulated. The most interesting information on such changes was obtained by cryo-EM of various ribosomal complexes with the ligands and by combination of rRNA site-directed mutagenesis with the analysis of structural changes in ribosome by chemical modification technique (chemical probing). The most studied structural transformations of the ribosome interacting with tRNAs and elongation factors are considered in this review. The structural rearrangements are discussed in the context of interactions between the functional centers of the ribosome. We also describe the system of tertiary contacts between the rRNA helices and proteins which forms the universal structure in the ribosome. We pay attention that by means of such system the allosteric conformational signal can be transmitted between the functional centers. Besides the discussion of different biochemical data in the scope of structural data we also consider the hypothesis that the position of GTPase associated center (GAC) in the ribosome regulates the binding of elongation factors.

Abstract
Protein biosynthesis is a complex biochemical process. It integrates multiple steps where different translation factors specifically interact with the ribosome in a precisely defined order. Among the translation factors one can find multiple GTP-binding or G-proteins. Their functioning is accompanied by GTP hydrolysis to the GDP and inorganic phosphate ion Pi. Ribosome stimulates the GTPase activity of the translation factors, thus playing a role analogues to GTPase-activating proteins (GAP). Translation factors--GTPases interact with the ribosome at all stages of protein biosynthesis. Initiation factor 2 (IF2) catalyse initiator tRNA binding to the ribosomal P-site and subsequent subunit joining. Elongation factor Tu (EF-Tu) is responsible for the aminoacyl-tRNA binding to the ribosomal A-site, while elongation factor G (EF-G) catalyses translocation of mRNA in the ribosome by one codon, accompanied by tRNA movement between the binding sites. In its turn, release factor 3 (RF3) catalyse dissociation of the ribosomal complex with release factors 1 or 2 (RF1 or RF2) following the peptide release. This review is devoted to the functional peculiarities of translational GTPases as related to other G-proteins. Particularly, to the putative GTPase activation mechanism, structure and functional cycles.

Abstract
Photoreactive derivatives of tRNAs, containing 6-thioguanosine or diazirine derivative of 5-methyleneaminouridine were compared as probes to modify Escherichia coli ribosomes. The derivatives of tRNA were synthesized by T7 transcription Proportion of the modified nucleotide analogues was optimised to obtain good yield, analogue incorporation and binding to the ribosome. Complexes of the tRNA analogues with the ribosomal P-site were irradiated with mild UV light. Cross-links were analysed by oligonucleotide-directed hydrolysis of rRNA by RNase H and reverse transcription. 6-thioguanosine was proved to be a perspective reagent for cross-linking studies of complex ribonucleoproteides.

Abstract
In the recently published X-ray crystallographic structure for the 50S subunit of Haloarcula marismortui ribosomes, residue U2546 of the 23S rRNA forms a non-Watson-Crick base pair with U2610. The corresponding residues in the secondary structure of the Escherichia coli 23S molecule are U2511 and C2575, and it follows that the latter base (C2575) should be protonated in order to form a base pair that is isostructural with its counterpart in H.marismortui. This prediction was demonstrated experimentally by reduction with sodium borohydride followed by primer extension analysis; borohydride is able to reduce positively charged bases, yielding products which block reverse transcription. In the course of the analysis a further charged base pair (AH(+)1528-G1543) was identified in the E.coli 23S molecule. Both charged pairs (U2511-CH(+)2575 and AH(+)1528-G1543) were only observed in the context of the intact ribosomal subunit and were not seen in deproteinized rRNA.

Abstract
rRNAs are the central players in the reactions catalyzed by ribosomes, and the individual rRNAs are actively involved in different ribosome functions. Our previous demonstration that yeast 5S rRNA mutants (called mof9) can impact translational reading frame maintenance showed an unexpected function for this ubiquitous biomolecule. At the time, however, the highly repetitive nature of the genes encoding rRNAs precluded more detailed genetic and molecular analyses. A new genetic system allows all 5S rRNAs in the cell to be transcribed from a small, easily manipulated plasmid. The system is also amenable for the study of the other rRNAs, and provides an ideal genetic platform for detailed structural and functional studies. Saturation mutagenesis reveals regions of 5S rRNA that are required for cell viability, translational accuracy, and virus propagation. Unexpectedly, very few lethal alleles were identified, demonstrating the resilience of this molecule. Superimposition of genetic phenotypes on a physical map of 5S rRNA reveals the existence of phenotypic clusters of mutants, suggesting that specific regions of 5S rRNA are important for specific functions. Mapping these mutants onto the Haloarcula marismortui large subunit reveals that these clusters occur at important points of physical interaction between 5S rRNA and the different functional centers of the ribosome. Our analyses lead us to propose that one of the major functions of 5S rRNA may be to enhance translational fidelity by acting as a physical transducer of information between all of the different functional centers of the ribosome.

Abstract
The data on RNA-RNA interactions between the components of the E. coli translation machinery obtained by X-ray crystallography and chemical methods are compared. The approaches to the study of RNA secondary and tertiary structure are assessed. The following conclusions are made: comparative sequence analysis and compensatory mutations approach both give reliable data on the RNA secondary structure. The chemical modification technique provides good results. Local cleavage of internucleotide bonds by hydroxyl radicals is reliable in the frame of its 40 A resolution, in contrast to the application of copper-phenanthroline complex as a cleavage reagent, which is unreliable. Direct UV irradiation and nitrogen mustard treatment are the best methods of crosslink generation. In vitro transcription is the only good method for the incorporation of nucleotide analogs in RNA. RNase H hydrolysis and/or nucleotide-specific RNases fingerprints must be applied for the crosslink site determination in parallel with reverse transcription.

Abstract
The proximity of loop D of 5 S rRNA to two regions of 23 S rRNA, domain II involved in translocation and domain V involved in peptide bond formation, is known from previous cross-linking experiments. Here, we have used site-directed mutagenesis and chemical probing to further define these contacts and possible sites of communication between 5 S and 23 S rRNA. Three different mutants were constructed at position A960, a highly conserved nucleotide in domain II previously crosslinked to 5 S rRNA, and the mutant rRNAs were expressed from plasmids as homogeneous populations of ribosomes in Escherichia coli deficient in all seven chromosomal copies of the rRNA operon. Mutations A960U, A960G and, particularly, A960C caused structural rearrangements in the loop D of 5 S rRNA and in the peptidyltransferase region of domain V, as well as in the 960 loop itself. These observations support the proposal that loop D of 5 S rRNA participates in signal transmission between the ribosome centers responsible for peptide bond formation and translocation.
