WebbAbstract. The chemical identity of RNA molecules beyond the four standard ribonucleosides has fascinated scientists since pseudouridine was characterized as the “fifth” ribonucleotide in 1951. Since then, the ever-increasing number and complexity of modified ribonucleosides have been found in viruses and throughout all three domains … Webb2 okt. 2024 · Ribonucleotide monophosphatase NagD, HAD superfamily [Nucleotide transport and metabolism] Links.
