MetabolomicsNeuronal tRNA modifications in Aplysia californica are repatterned during behavioral habituation
Transfer RNA (tRNA) modifications have been increasingly implicated as post-transcriptional regulators of basic neuronal functions. However, characterizing tRNA modification profiles in specific neural circuits that control well-defined behaviors is notoriously difficult due to the complexity of con...

MetabolomicsRNA modification dynamics during Enterococcus faecalis OG1RF growth
Quantitative analysis of relative levels of RNA modifications in small (primarily tRNA) and large (primarily 16S/23S rRNA) RNAs isolated from Enterococcus faecalis OG1RF across a growth time course in BHI media.

MetabolomicsN6-methyladenosine modification is not a general trait of positive-sense RNA viral genomes

Despite the nuclear localization of the m6A machinery, the genomes of multiple exclusively-cytoplasmic RNA viruses, such as chikungunya (CHIKV) and dengue (DENV), are reported to be extensively m6A-modified. However, these findings are mostly based on m6A-seq, an antibody-dependent technique with...

TranscriptomicsLoss of a Conserved tRNA Anticodon Modification Perturbs Cellular Signaling
Transfer RNA (tRNA) modifications enhance the efficiency, specificity and fidelity of translation in all organisms. The anticodon modification mcm5s2U34 is required for normal growth and stress resistance in yeast; mutants lacking this modification have numerous phenotypes. Mutations in the homologo...

TranscriptomicsA growth-essential Tetrahymena Piwi protein carries tRNA fragment cargo
Argonaute/Piwi proteins associate with small RNAs that typically provide sequence specificity for RNP function in gene and genome regulation. Here we show that Twi12, a Tetrahymena Piwi protein essential for growth, is loaded with mature tRNA fragments. The tightly bound ~18-22 nt tRNA 3M-bM-^@M-^Y ...

TranscriptomicsIdentification of tRNA sequences in Lactococcus lactis
we report the identification and sequences of the tRNAome of industrially relevant microorganism Lactococcus lactis Three Next Generation sequencing runs annotated as S1, S2 and S3 were performed. Cells were harvested at exponential phase and tRNA was isolated. S1 and S2 were spiked with Phe-tRNAGAA...

ProteomicsMapping the tRNA Modification Landscape of Bartonella henselae Houston I and Bartonella quintana Toulouse
Transfer RNA (tRNA) modifications play a crucial role in maintaining translational fidelity and efficiency, and they may function as regulatory elements in stress response and virulence. Despite their pivotal roles, a comprehensive mapping of tRNA modifications and their associated synthesis genes i...

MetabolomicsVirus-induced codon-specific reprogramming to favor viral RNA translation
Recent evidence indicates that codon usage bias regulates gene expression. How viruses, such as the emerging mosquito-borne Chikungunya virus (CHIKV), express their genomes at high levels despite an enrichment in rare codons remains a puzzling question. Using ribosome footprinting, here we analysed ...

GenomicsSuppressor mutant screening lacking growth-essential tRNA modification in bacteria
Post-transcriptional modifications are important for transfer RNAs (tRNAs) to be efficient and accurate in translation on the ribosome. The m1G37 modification on a subset of tRNAs in bacteria are generated by a conserved methyltransferase TrmD and is essential for bacterial growth. Previous studies ...

ProteomicstRNA modification profile of PA14 transposon insertion mutant library
Transfer RNA (tRNA) modifications have emerged as critical posttranscriptional regulators of gene expression that impact diverse biological and disease processes. While there is extensive knowledge about the enzymes installing the dozens of tRNA modifications – the tRNA epitranscriptome – very littl...
