The nucleotide sequence of a spinach chloroplast proline tRNA (sp. chl. tRNApro) has been determined. This tRNA shows more overall homology to phage T4 proline tRNA (61% homology) than to eukaryotic proline tRNAs (53% homology) or mitochondrial proline tRNAs (36-49% homology). Sp. chl. tRNApro, like all other chloroplast tRNAs sequenced, contains a methylated GG sequence in the dihyrouridine loop and lacks unusual structural features which have been found in many mitochondrial tRNAs.
已确定菠菜叶绿体脯氨酸转运核糖核酸(sp. chl. tRNApro)的核苷酸序列。与真核生物脯氨酸转运核糖核酸(同源性为53%)或线粒体脯氨酸转运核糖核酸(同源性为36 - 49%)相比,这种转运核糖核酸与噬菌体T4脯氨酸转运核糖核酸的整体同源性更高(同源性为61%)。与所有其他已测序的叶绿体转运核糖核酸一样,sp. chl. tRNApro在二氢尿嘧啶环中含有一个甲基化的GG序列,并且缺乏许多线粒体转运核糖核酸中发现的异常结构特征。
