Summary
This study investigates tRNA arrays in the Mycobacterium genus, now divided into five genera. Researchers characterized tRNA array diversity across these new genera, suggesting a role in organismal fitness.
Area of Science:
- Microbiology
- Genomics
- Bioinformatics
Background:
- tRNA arrays, regions of high tRNA gene density, are known in the Mycobacterium genus.
- Recent phylogenomics reclassified Mycobacterium into five distinct genera.
- Understanding tRNA array distribution in these new genera is crucial.
Purpose of the Study:
- To identify and characterize tRNA array units within the newly defined genera: Mycobacterium, Mycolicibacterium, Mycolicibacillus, and Mycobacteroides.
- To analyze the abundance and diversity of these tRNA arrays.
- To explore the potential functional significance of tRNA arrays in Actinobacteria.
Main Methods:
- In-silico analysis of genomic data.
- Phylogenomic comparison across related bacterial genera.
- Bioinformatic characterization of tRNA array structures and copy numbers.
Main Results:
- tRNA arrays were identified and characterized across the genera Mycobacterium, Mycolicibacterium, Mycolicibacillus, and Mycobacteroides.
- Variations in tRNA array abundance and diversity were observed among these genera.
- The prevalence of tRNA arrays was noted within the broader Actinobacteria phylum.
Conclusions:
- The study provides a comprehensive characterization of tRNA arrays in the recently redefined Mycobacterium-related genera.
- Findings suggest tRNA arrays are a conserved feature with potential roles in bacterial fitness.
- Further research is warranted to elucidate the specific functions of tRNA arrays in Actinobacteria.

Aminoacyl-tRNA synthetases are present in both eukaryotes and bacteria. Though eukaryotes have 20 different aminoacyl-tRNA synthetases to couple to 20 amino acids, many bacteria do not have genes for all of these aminoacyl-tRNA synthetases. Despite this, they still use all 20 amino acids to synthesize their proteins. For instance, some bacteria do not have the gene encoding the enzyme that couples glutamine with its partner tRNA. In these organisms, one enzyme adds glutamic acid to all of the...

One of the unique features of tRNA is the presence of modified bases. In some tRNAs, modified bases account for nearly 20% of the total bases in the molecule. Altogether, these unusual bases protect the tRNA from enzymatic degradation by RNases.
Each of these chemical modifications is carried by a specific enzyme, post-transcription. All of these enzymes have unique base and site-specificity. Methylation, the most common chemical modification, is carried by at least nine different enzymes, with...

14.1K
Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

03:06From DNA to Protein
22.2K
The flow of genetic information in cells from DNA to mRNA to protein is described by the central dogma, which states that genes specify the sequence of mRNAs, which in turn specify the sequence of amino acids making up all proteins. The decoding of one molecule to another is performed by specific proteins and RNAs. Because the information stored in DNA is so central to cellular function, it makes intuitive sense that the cell would make mRNA copies of this information for protein synthesis...

Initiating translation is complex because it involves multiple molecules. Initiator tRNA, ribosomal subunits, and eukaryotic initiation factors (eIFs) are all required to assemble on the initiation codon of mRNA. This process consists of several steps that are mediated by different eIFs.
First, the initiator tRNA must be selected from the pool of elongator tRNAs by eukaryotic initiation factor 2 (eIF2). The initiator tRNA (Met-tRNAi) has conserved sequence elements including modified bases at...
