Structural characterization of four ribose-methylated nucleosides from the transfer RNA of extremely thermophilic archaebacteria
Abstract
Structures of the ribose-methylated nucleosides 5,2′-O-dimethylcytidine (1), N4-acetyl-2′-O-methylcytidine (2), 2-thio-2′-O-methyluridine (3), and N2,N2,2′-O-trimethylguanosine (4) from the transfer RNA of Sulfolobus solfataricus, Thermoproteus neutrophilus, and Pyrodictium occultum have been established, and verified by chemical synthesis.
