Selective Chemical Manipulation of Mannosyl- and Galactosyl-Queuosine in tRNAs of Living Cells
{{output}}
Queuosine is a hypermodified nucleoside found in the anticodon loop of tRNAs decoding the amino acids His, Asn, Tyr, and Asp. In tRNATyr, the homoallylic 2-hydroxyl group of the cyclopentene ring carries an additional β-galactose, while in tRNAAsp, an α-mann... ...
