A novel modified nucleoside located in the first position of the anticodon of yeast tRNAVal2a was isolated and its chemical structure was characterized as 5-carbamoylmethyluridine by means of ultraviolet absorption spectrum, mass spectrum, and nuclear magnetic resonance spectrum.
从酵母tRNAVal2a反密码子第一位分离出一种新型修饰核苷,通过紫外吸收光谱、质谱和核磁共振光谱对其化学结构进行表征,确定为5-氨甲酰基甲基尿苷。
