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, ...
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 ...
