Abstract
In most eukaryotic genomes, tandemly repeated copies of 5S rRNA genes are clustered outside the nucleolus organizer region (NOR), which normally encodes three other major rRNAs: 18S, 5.8S, and 28S. Our analysis of turtle rDNA sequences has revealed a 5S rDNA insertion into the NOR intergenic spacer in antisense orientation. The insertion (hereafter called NOR-5S rRNA gene) has a length of 119 bp and coexists with the canonical 5S rDNA clusters outside the NOR. Despite the ∼20% nucleotide difference between the two 5S gene sequences, their internal control regions for RNA polymerase III are similar. Using the turtle Trachemys scripta as a model species, we showed the NOR-5S rDNA specific expression in oocytes. This expression is concurrent with the NOR rDNA amplification during oocyte growth. We show that in vitellogenic oocytes, the NOR-5S rRNA prevails over the canonical 5S rRNA in the ribosomes, suggesting a role of modified ribosomes in oocyte-specific translation. The orders Testudines and Crocodilia seem to be the only taxa of vertebrates with such a peculiar rDNA organization. We speculate that the amplification of the 5S rRNA genes as a part of the NOR DNA during oogenesis provides a dosage balance between transcription of all the four ribosomal RNAs while producing a maternal pool of extra ribosomes. We further hypothesize that the NOR-5S rDNA insertion appeared in the Archelosauria clade during the Permian period and was lost later in the ancestors of Aves.

Abstract
Arginyltransferase ATE1 mediates posttranslational arginylation and plays key roles in multiple physiological processes. ATE1 utilizes arginyl (Arg)-tRNAArg as the donor of Arg, putting this reaction into a direct competition with the protein synthesis machinery. Here, we address the question of ATE1- Arg-tRNAArg specificity as a potential mechanism enabling this competition in vivo. Using in vitro arginylation assays and Ate1 knockout models, we find that, in addition to full-length tRNA, ATE1 is also able to utilize short tRNAArg fragments that bear structural resemblance to tRNA-derived fragments (tRF), a recently discovered class of small regulatory non-coding RNAs with global emerging biological role. Ate1 knockout cells show a decrease in tRFArg generation and a significant increase in the ratio of tRNAArg:tRFArg compared with wild type, suggesting a functional link between tRFArg and arginylation. We propose that generation of physiologically important tRFs can serve as a switch between translation and protein arginylation.

Abstract
Background The possibility of validating biological macromolecules with locally disordered domains like RNA against solution properties is helpful to understand their function. In this work, we present a computational scheme for predicting global properties and mimicking the internal dynamics of RNA molecules in solution. A simple coarse-grained model with one bead per nucleotide and two types of intra-molecular interactions (elastic interactions and excluded volume interactions) is used to represent the RNA chain. The elastic interactions are modeled by a set of Hooke springs that form a minimalist elastic network. The Brownian dynamics technique is employed to simulate the time evolution of the RNA conformations. Results That scheme is applied to the 5S ribosomal RNA of E. Coli and the yeast phenylalanine transfer RNA. From the Brownian trajectory, several solution properties (radius of gyration, translational diffusion coefficient, and a rotational relaxation time) are calculated. For the case of yeast phenylalanine transfer RNA, the time evolution and the probability distribution of the inter-arm angle is also computed. Conclusions The general good agreement between our results and some experimental data indicates that the model is able to capture the tertiary structure of RNA in solution. Our simulation results also compare quite well with other numerical data. An advantage of the scheme described here is the possibility of visualizing the real time macromolecular dynamics.

Abstract
BACKGROUND In plants, the 5 S rRNA genes usually occur as separate tandems (S-type arrangement) or, less commonly, linked to 35 S rDNA units (L-type). The activity of linked genes remains unknown so far. We studied the homogeneity and expression of 5 S genes in several species from family Asteraceae known to contain linked 35 S-5 S units. Additionally, their methylation status was determined using bisulfite sequencing. Fluorescence in situ hybridization was applied to reveal the sub-nuclear positions of rDNA arrays. RESULTS We found that homogenization of L-type units went to completion in most (4/6) but not all species. Two species contained major L-type and minor S-type units (termed L(s)-type). The linked genes dominate 5 S rDNA expression while the separate tandems do not seem to be expressed. Members of tribe Anthemideae evolved functional variants of the polymerase III promoter in which a residing C-box element differs from the canonical angiosperm motif by as much as 30%. On this basis, a more relaxed consensus sequence of a plant C-box: (5'-RGSWTGGGTG-3') is proposed. The 5 S paralogs display heavy DNA methylation similarly as to their unlinked counterparts. FISH revealed the close association of 35 S-5 S arrays with nucleolar periphery indicating that transcription of 5 S genes may occur in this territory. CONCLUSIONS We show that the unusual linked arrangement of 5 S genes, occurring in several plant species, is fully compatible with their expression and functionality. This extraordinary 5 S gene dynamics is manifested at different levels, such as variation in intrachromosomal positions, unit structure, epigenetic modification and considerable divergence of regulatory motifs.

Abstract
Among eukaryotes two types of nuclear ribosomal DNA (nrDNA) organization have been observed. Either all components, i.e. the small ribosomal subunit, 5.8S, large ribosomal subunit, and 5S occur tandemly arranged or the 5S rDNA forms a separate cluster of its own. Generalizations based on data derived from just a few model organisms have led to a superimposition of structural and evolutionary traits to the entire plant kingdom asserting that plants generally possess separate arrays. This study reveals that plant nrDNA organization into separate arrays is not a distinctive feature, but rather assignable almost solely to seed plants. We show that early diverging land plants and presumably streptophyte algae share a co-localization of all rRNA genes within one repeat unit. This raises the possibility that the state of rDNA gene co-localization had occurred in their common ancestor. Separate rDNA arrays were identified for all basal seed plants and water ferns, implying at least two independent 5S rDNA transposition events during land plant evolution. Screening for 5S derived Cassandra transposable elements which might have played a role during the transposition events, indicated that this retrotransposon is absent in early diverging vascular plants including early fern lineages. Thus, Cassandra can be rejected as a primary mechanism for 5S rDNA transposition in water ferns. However, the evolution of Cassandra and other eukaryotic 5S derived elements might have been a side effect of the 5S rDNA cluster formation. Structural analysis of the intergenic spacers of the ribosomal clusters revealed that transposition events partially affect spacer regions and suggests a slightly different transcription regulation of 5S rDNA in early land plants. 5S rDNA upstream regulatory elements are highly divergent or absent from the LSU-5S spacers of most early divergent land plant lineages. Several putative scenarios and mechanisms involved in the concerted relocation of hundreds of 5S rRNA gene copies are discussed.

Abstract
The ribosome is a large complex containing both protein and RNA which must be assembled in a precise manner to allow proper functioning in the critical role of protein synthesis. 5S rRNA is the smallest of the RNA components of the ribosome, and although it has been studied for decades, we still do not have a clear understanding of its function within the complex ribosome machine. It is the only RNA species that binds ribosomal proteins prior to its assembly into the ribosome. Its transport into the nucleolus requires this interaction. Here we present an overview of some of the key findings concerning the structure and function of 5S rRNA and how its association with specific proteins impacts its localization and function.

Abstract
The presence of CTC family proteins is a unique feature of bacterial cells. In the CTC family, there are true ribosomal proteins (found in ribosomes of exponentially growing cells), and at the same time there are also proteins temporarily associated with the ribosome (they are produced by the cells under stress only and incorporate into the ribosome). One feature is common for these proteins - they specifically bind to 5S rRNA. In this review, the history of investigations of the best known representatives of this family is described briefly. Structural organization of the CTC family proteins and their occurrence among known taxonomic bacterial groups are discussed. Structural features of 5S rRNA and CTC protein are described that predetermine their specific interaction. Taking into account the position of a CTC protein and its intermolecular contacts in the ribosome, a possible role of its complex with 5S rRNA in ribosome functioning is discussed.

Abstract
A specific complex of 5 S rRNA and several ribosomal proteins is an integral part of ribosomes in all living organisms. Here we studied the importance of Escherichia coli genes rplE, rplR and rplY, encoding 5 S rRNA-binding ribosomal proteins L5, L18 and L25, respectively, for cell growth, viability and translation. Using recombineering to create gene replacements in the E. coli chromosome, it was shown that rplE and rplR are essential for cell viability, whereas cells deleted for rplY are viable, but grow noticeably slower than the parental strain. The slow growth of these L25-defective cells can be stimulated by a plasmid expressing the rplY gene and also by a plasmid bearing the gene for homologous to L25 general stress protein CTC from Bacillus subtilis. The rplY mutant ribosomes are physically normal and contain all ribosomal proteins except L25. The ribosomes from L25-defective and parental cells translate in vitro at the same rate either poly(U) or natural mRNA. The difference observed was that the mutant ribosomes synthesized less natural polypeptide, compared to wild-type ribosomes both in vivo and in vitro. We speculate that the defect is at the ribosome recycling step.

Abstract
The article presents translational and rotational diffusion coefficients of 5S rRNA determined experimentally by the method of dynamic light scattering (DLS) and its comparison with the values predicted for different models of this molecule. The tertiary structure of free 5S rRNA was proposed on the basis of the atomic structures of the 5S rRNA from E. coli and H. marismortui extracted from the ribosome. A comparison of the values of DT, tauR, and Rg predicted for different models with experimental results for the free molecule in solution suggests that free 5S rRNA is less compact than that in the complex with ribosomal proteins. In general, the molecules of 5S rRNA consist of three domains: a short one and two longer ones. As follows from a comparison of the results of our simulations with experimental values, in the molecule in solution the two closest helical fragments of the longer domains remain collinear, whereas the short domain takes a position significantly deviated from them.

Abstract
Ribosomes have been visualized in electron micrographs in 1943 but 5S rRNA was discovered 20 years later. The next four decades witnessed big advances in our understanding of the ribosome using biochemical, genetic and low resolution structural approaches. During those times many experimental data accumulates also on 5S rRNA, but its precise function remains unknown. To understand the role of this RNA in ribosome a high-resolution structure is urgently needed. Because the ribosome is a dynamic machine, details on the interaction of 5S rRNA with proteins within entire ribosome are required. Big progress in the structural analysis of ribosome will stimulate further understanding of 5S rRNA.

Abstract
A Northwestern analysis of Escherichia coli total proteins with radiolabeled 5S rRNA identified two novel 5S rRNA interacting proteins, a 70 kDa and a 37 kDa protein, and three ribosomal proteins reported on already. The N-terminal sequencing of the 70 kDa protein separated by SDS-PAGE from the high-salt-washed fraction of crude ribosome led to the discovery of a polypeptide identical in its first 10 amino acid residues to E. coli heat shock protein 70. The N-terminal eight amino acid sequence of the 37 kDa protein extracted from the high-salt-washed ribosome is identical to that of the ribosomal protein L2. In addition, the interaction of these proteins with 5S rRNA has been confirmed with gel mobility shift assays.

Abstract
The structure-function relationship in RNA molecules is a key to understanding of the expression of genetic information. Various types of RNA play crucial roles at almost every step of protein biosynthesis. In recent years, it has been shown that one of the most important structural elements in RNA is a wobble pair G-U. In this paper, we present for the first time an analysis of the distribution of G-U pairs in eukaryotic 5S ribosomal RNAs. Interestingly, the G-U pair in 5S rRNA species is predominantly found in two intrahelical regions of the stems I and V and at the junction of helix IV and loop A. The distribution of G-U pairs and the nature of adjacent bases suggests their possible role as a recognition site in interactions with other components of protein biosynthesis machinery.

Abstract
Transcription factor IIIA (TF IIIA) binds and specifically activates transcription of eukaryotic 5S rRNA genes. It also forms a 7S ribonucleoprotein complex with mature 5S rRNA. Here, we describe the purification and properties of pTF IIIA from higher plants. The purified protein from tulip (Tulipa whittalii) has a molecular mass of about 40 kDa and also binds 5S rRNA and 5S rRNA genes. pTF IIIA also facilitates the transcription of a 5S rRNA gene in a HeLa cell extract.

Abstract
5S Ribosomal RNA is the smallest RNA component of the ribosomes. Due to relatively simple isolation and sequencing procedures as well as a potential use of the sequence data in evolutionary analyses, the amount of known nucleotide sequences on both RNA and DNA levels was rapidly growing. In this paper we present the updated (March 1996) compilation of eukaryotic 5D rRNA and 5S rDNA sequences.

Abstract
The compilation of 5S rRNA and 5S rRNA gene nucleotide sequences as of 30 September 1996, contains a total of 1661 primary structures of 5S rRNAs or their genes, which is an increase of 928 new sequence entries over the last compilation. It covers sequences from 54 archaea, 449 eubacteria, 34 plastids, nine mitochondria and 430 eukaryotes. The databank uses the format of the EMBL Nucleotide Sequence Data Library complemented by a Sequence Alignment (SA) field including secondary structure information. The taxonomic classification of organisms was totally updated. Now the database is also available via anonymous FTP or WWW.
