Abstract:

To date, numerous modified nucleosides in tRNA as well as tRNA modification enzymes have been identified not only in thermophiles but also in mesophiles. Because most modified nucleosides in tRNA from thermophiles are common to those in tRNA from mesophiles, they are considered to work essentially in steps of protein synthesis at high temperatures. At high temperatures, the structure of unmodified tRNA will be disrupted. Therefore, thermophiles must possess strategies to stabilize tRNA structures. To this end, several thermophile-specific modified nucleosides in tRNA have been identified. Othe

Abstract:

Abstract. The tRNA modification gene in eukaryotes is relatively conservative. As an important modification gene, the TRDMT1 gene plays an important role in maintaining tRNA structural maintenance and reducing mistranslation of protein translation by methylation of specific tRNA subpopulations. Mouse and zebrafish TRDMT1 knockout experiments indicate that it may mediate growth and development through tRNA modification. However, there are no systematic reports on the function of tRNA-modified genes in livestock. In this study, Qinchuan cattle DNA pool sequencing technology was used. A G>C mu

Abstract:

More than 90 different modified nucleosides have been identified in tRNA. Among the tRNA modifications, the 7-methylguanosine (m7G) modification is found widely in eubacteria, eukaryotes, and a few archaea. In most cases, the m7G modification occurs at position 46 in the variable region and is a product of tRNA (m7G46) methyltransferase. The m7G46 modification forms a tertiary base pair with C13-G22, and stabilizes the tRNA structure. A reaction mechanism for eubacterial tRNA m7G methyltransferase has been proposed based on the results of biochemical, bioinformatic, and structural studies. How

Abstract:

The factors and mechanisms that govern tRNA stability in bacteria are not well understood. Here, we investigated the influence of posttranscriptional modification of bacterial tRNAs (tRNA modification) on tRNA stability. We focused on ThiI-generated 4-thiouridine (s4U), a modification found in bacterial and archaeal tRNAs. Comprehensive quantification ofVibrio choleraetRNAs revealed that the abundance of some tRNAs is decreased in a ΔthiIstrain in a stationary phase-specific manner. Multiple mechanisms, including rapid degradation of a subset of hypomodified tRNAs, account for the reduced abun

Abstract:

Cellular RNAs are chemically modified by many RNA modification enzymes; however, often the functions of modifications remain unclear, such as for pseudouridine formation in the tRNA TΨC arm by the bacterial tRNA pseudouridine synthase TruB. Here we test the hypothesis that RNA modification enzymes also act as RNA chaperones. Using TruB as a model, we demonstrate that TruB folds tRNA independent of its catalytic activity, thus increasing the fraction of tRNA that can be aminoacylated. By rapid kinetic stopped-flow analysis, we identified the molecular mechanism of TruB’s RNA chaperone activity:

Abstract:

Transfer RNA (tRNA) is subject to a multitude of posttranscriptional modifications which can profoundly impact its functionality as the essential adaptor molecule in messenger RNA (mRNA) translation. Therefore, dynamic regulation of tRNA modification in response to environmental changes can tune the efficiency of gene expression in concert with the emerging epitranscriptomic mRNA regulators. Several of the tRNA modifications are required to prevent human diseases and are particularly important for proper development and generation of neurons. In addition to the positive role of different tRNA

Abstract:

Dictyostelium discoideum is a social amoeba, which on starvation develops from a single-cell state to a multicellular fruiting body. This developmental process is accompanied by massive changes in gene expression, which also affect non-coding RNAs. Here, we investigate how tRNAs as key regulators of the translation process are affected by this transition. To this end, we used LOTTE-seq to sequence the tRNA pool of D. discoideum at different developmental time points and analyzed both tRNA composition and tRNA modification patterns. We developed a workflow for the specific detection of modifica

Abstract:

Neisseria gonorrhoeae (Ng) encounters different microenvironments during its life-cycle. Some of these niches have different concentrations of oxygen, which influences the rate of Ng growth; as well as iron, an element essential for Ng survival. Differential expression of several proteins allows the bacteria to adapt to the diverse conditions it comes encounters. One protein affected by environmental changes during Ng growth is Gcp, a tRNA-modification enzyme essential for protein synthesis. To study the regulation of expression of Gcp, we first analyzed the sequence of its ORF, gcp. Orthologs

Abstract:

Stable RNAs undergo a wide variety of post-transcriptional modifications, that add to the functional repertoire of these molecules. Some of these modifications are catalyzed by stand-alone protein enzymes, while some others are catalyzed by RNA-protein complexes. tRNAs from all domains of life contain many such modifications, that increase their structural stability and refine their decoding properties. Certain regions of tRNAs are more frequently modified than others. Two such regions are the anticodon loop, and the TψC stem. In the halophilic euryarchaeon Haloferax volcanii, tRNATrp and tRNA

Abstract:

Enterococci were once thought to be harmless, commensal organisms that colonize the gastrointestinal tract of humans and other mammals. In the last 30 years, however, concern has grown in the clinical setting over two particular species, Enterococcus faecalis and Enterococcus faecium, which are frequently found to be the etiologic agents of nosocomial infections. Aminoacyl-phosphatidylglycerol synthases (aaPGSs) are integral membrane proteins that add amino acids to phosphatidylglycerol (PG) in the cellular envelope of bacteria. Addition of amino acids to PG confers resistance to various thera
