Sulfur-containing nucleoside from yeast transfer ribonucleic acid: 2-thio-5(or 6)-uridine acetic acid methyl ester

L Baczynskyj et al. Science. .

Abstract

A nucleoside, isolated from yeast transfer RNA, has been assigned the structure 2-thio-5-uridine acetic acid methyl ester on the basis of high-esolution mass spectrometry, chemical properties, and ultraviolet spectra. The alternate 6-substituted isomeric structure cannot yet be completely ruled out.
