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 ...
Crystal structure of glutaminyl tRNA synthetase (GlnRS, green) in complex with its substrate tRNA^Gln (yellow). Left panel: Color-coded residues depict favorable (blue) and unfavorable (red) effects ...
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 ...
