The structure of a key enzyme involved in protein production is revealed by cryo-electron microscopy (cryo-EM). Using cryo-EM, researchers at Goethe University (Frankfurt, Germany) shed light on ...

In all living organisms, the biomolecule transfer RNA (tRNA) plays a fundamental role in protein production. tRNAs are generated from precursor molecules in several steps. The enzyme tRNA splicing ...

Archaeosine is a modified nucleoside found only in the tRNAs from archaea, the so-called third domain of life, and contributes to the maintenance of the L-shaped tRNA three-dimensional structure. The ...

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 ...

Researchers say discoveries could expand the CRISPR toolbox and lead to more efficient, rapid diagnostic tools for detecting COVID-19, influenza, and RSV.

Researchers uncovered a previously unknown CRISPR immune response in bacteria that targets transfer RNAs. The newly ...

A novel CRISPR defense mechanism, unlike known nucleases, specifically destroys transfer ribonucleic acids (tRNA) that are ...
