Anticodon Wobble Uridine Modification by Elongator at the Crossroad of Cell Signaling, Differentiation, and Diseases

open access: yesEpigenomes, 2020
First identified 20 years ago as an RNA polymerase II-associated putative histone acetyltransferase, the conserved Elongator complex has since been recognized as the central player of a complex, regulated, and biologically relevant epitranscriptomic ...

Conflict between translation initiation and elongation in vertebrate mitochondrial genomes. [PDF]

open access: yesPLoS ONE, 2007
The strand-biased mutation spectrum in vertebrate mitochondrial genomes results in an AC-rich L-strand and a GT-rich H-strand. Because the L-strand is the sense strand of 12 protein-coding genes out of the 13, the third codon position is overall strongly

Chronic Progressive External Ophthalmoplegia Is Associated with a Novel Mutation in the Mitochondrial tRNA(Asn) Gene [PDF]

open access: yes, 1994
Chronic progressive external ophthalmoplegia (CPEO) is caused by a decreased oxidative phosphorylation (OXPHOS) activity due to large-scale deletions of the mitochondrial genome in 50 % of the patients.

The biogenesis pathway of tRNA-derived piRNAs in Bombyx germ cells. [PDF]

open access: yes, 2017
Transfer RNAs (tRNAs) function in translational machinery and further serves as a source of short non-coding RNAs (ncRNAs). tRNA-derived ncRNAs show differential expression profiles and play roles in many biological processes beyond translation ...

Codon Bias Patterns of $E.coli$'s Interacting Proteins [PDF]

open access: yes, 2015
Synonymous codons, i.e., DNA nucleotide triplets coding for the same amino acid, are used differently across the variety of living organisms. The biological meaning of this phenomenon, known as codon usage bias, is still controversial.

Functional plasticity of antibacterial EndoU toxins. [PDF]

open access: yes, 2018
Bacteria use several different secretion systems to deliver toxic EndoU ribonucleases into neighboring cells. Here, we present the first structure of a prokaryotic EndoU toxin in complex with its cognate immunity protein.

A rationale for tRNA modification circuits in the anticodon loop

open access: yesRNA: A publication of the RNA Society, 2018
The numerous post-transcriptional modifications of tRNA play a crucial role in tRNA function. While most modifications are introduced to tRNA independently, several sets of modifications are found to be interconnected such that the presence of one set of

High-affinity recognition of specific tRNAs by an mRNA anticodon-binding groove

open access: yesNature Structural & Molecular Biology, 2019
T-box riboswitches are modular bacterial noncoding RNAs that sense and regulate amino acid availability through direct interactions with tRNAs. Between the 5′ anticodon-binding stem I domain and the 3′ amino acid sensing domains of most T-boxes lies the ...

Importance of a tRNA anticodon loop modification and a conserved, noncanonical anticodon stem pairing in tRNACGGPro for decoding

open access: yesJournal of Biological Chemistry, 2019
Modification of anticodon nucleotides allows tRNAs to decode multiple codons, expanding the genetic code. Additionally, modifications located in the anticodon loop, but outside the anticodon itself, stabilize tRNA–codon interactions, increasing decoding ...

S. cerevisiae Trm140 has two recognition modes for 3-methylcytidine modification of the anticodon loop of tRNA substrates

open access: yesRNA: A publication of the RNA Society, 2017
The 3-methylcytidine (m3C) modification is ubiquitous in eukaryotic tRNA, widely found at C32 in the anticodon loop of tRNAThr, tRNASer, and some tRNAArg species, as well as in the variable loop (V-loop) of certain tRNASer species.
