Thus, ArcS is an unprecedented tRNA modification enzyme that can act on a nucleoside as the substrate. With the development of mRNA vaccines for COVID-19, modified nucleosides like pseudouridine and 1 ...

All living organisms encode the amino acid sequences of proteins as nucleotide sequences (genetic information) in their genomic DNA. The genetic information is transcribed and subsequently translated ...

A study conducted by a research team from Kumamoto University has shed light on the critical role of a tRNA methylation enzyme, TRMT10A, in supporting brain function. The findings reveal how the ...

A groundbreaking study has shed light on the critical role of a tRNA methylation enzyme, TRMT10A, in supporting brain function. The findings reveal how the absence of TRMT10A leads to a reduction in ...

Researchers have developed a powerful tool capable of scanning thousands of biological samples to detect transfer ribonucleic acid (tRNA) modifications—tiny chemical changes to RNA molecules that help ...

The ribosome, that protein-making machine, relies on other, smaller machines. For example, it works in concert with a mechanism that supplies amino-acid-carrying tRNAs, including tRNAs that require ...

RNA plays critical roles in nearly all biological processes, but current methods for sequencing RNA are significantly limited. This is partially because RNA molecules are chemically modified within ...

Loss of TRMT10A led to a decrease in the levels of initiator methionine tRNA (tRNA iMet) and a specific glutamine tRNA (tRNA Gln). This reduction weakened the initiation of protein synthesis for ...

Archaeosine is synthesized via three steps in tRNA. ArcS, the second-step enzyme, transfers a lysine to preQ 0, which is introduced into tRNA by ArcTGT, the first-step enzyme. The resultant preQ 0-Lys ...
