Transfer RNA-derived small RNAs in the cancer transcriptome [PDF]

, 2016
The cellular lifetime includes stages such as differentiation, proliferation, division, senescence and apoptosis.These stages are driven by a strictly ordered process of transcription dynamics.

Differential expression of human tRNA genes drives the abundance of tRNA-derived fragments

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance Given the large genetic redundancy of transfer RNA (tRNA) genes, the physiological relevance of variations in expression levels of individual tRNA genes is unclear.

Protein O‐glycosylation in the Bacteroidota phylum

FEBS Open Bio, EarlyView.
Species of the Bacteroidota phylum exhibit a unique O‐glycosylation system. It modifies noncytoplasmic proteins on a specific amino acid motif with a shared glycan core but a species‐specific outer glycan. A locus of multiple glycosyltransferases responsible for the synthesis of the outer glycan has been identified.

15N NMR study of a mixture of uniformly labeled tRNAs [PDF]

, 1982
15N NMR spectra were taken of 15N-enriched tRNA extracted from bakers yeast; ammonium sulfate was used as a nitrogen source. The increase in the degree of denaturation of tRNA, which occurs with increase in temperature from 30 degrees C to 70 degrees C ...

Phosphomimetic mutations near active sites of proteins in Thermus thermophilus suggest a widespread regulatory mechanism

FEBS Open Bio, EarlyView.
In Thermus thermophilus, more than half of the phosphorylation sites identified by proteomic analysis are located near the active site. All phosphomimetic mutants of phosphosites of six enzymes belonging to different families showed severely reduced activity compared with the wild‐type, particularly in the turnover number.

Cells alter their tRNA abundance to selectively regulate protein synthesis during stress conditions

Science Signaling, 2018
Stress-induced changes in tRNA abundance enhance the translation efficiency of stress response proteins. The right proteins at the right time Cells must tailor protein synthesis so that proteins that enable growth and proliferation and those that enable ...

Microbial profile of the appendix niche in acute appendicitis: a novel sampling approach

FEBS Open Bio, EarlyView.
This study utilized a novel sampling method, ERAT (i.e. endoscopic retrograde appendicitis treatment)‐guided lumen aspiration, to obtain samples from the appendix, and shotgun metagenomic sequencing was performed for in situ characterization of the appendix microbiome in patients with acute appendicitis.
