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 ...
HARPs are the smallest known RNase P enzymes that help with tRNA maturation in bacteria and archaea. How such a small enzyme accomplishes this crucial task has baffled researchers for some time. Now, ...
A novel CRISPR defense mechanism, unlike known nucleases, specifically destroys transfer ribonucleic acids (tRNA) that are vital for protein production to shut down infected cells. (Nanowerk News) ...
In 1965, Cornell biochemist Robert Holley deciphered the 77 nucleotide sequence of transfer RNA. Three years later, Holley was awarded the Nobel Prize for this work, but already the race to determine ...
