RNA molecules can be modified by enzymes through the addition or removal of chemical groups, but the roles of these modifications in the regulation of both mRNAs and non-coding RNAs are not fully ...
Genetic information encoded in genomic DNA is transcribed to mRNAs and then the codons on mRNA are decoded by transfer RNAs (tRNAs) during protein synthesis. tRNAs deliver amino acids to ribosomes and ...
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 ...
Transfer RNAs (tRNAs) deliver specific amino acids to ribosomes during translation of messenger RNA into proteins. The abundance of tRNAs can therefore have a profound impact on cell physiology, but ...
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 ...
