Abstract
A compound present in bovine amniotic fluid, and which is a substrate for tRNA:guanine transglycosylase, has been structurally characterized as queuine, a hypermodified base which occurs in transfer RNA. The structure assignment is based on mass spectrometry, proton nuclear magnetic resonance, and ultraviolet absorbance data.
摘要
存在于牛羊水且作为tRNA：鸟嘌呤转糖基酶底物的一种化合物，在结构上已被鉴定为queuine，一种存在于转运RNA中的高度修饰碱基。该结构归属基于质谱、质子核磁共振和紫外吸收数据。
