The amino-acid compositions of the mitochondrial ribosomal subunits of Saccharomyces cerevisiae have been determined and compared to those of cytoplasmic ribosomal subunits. For the large subunits, the mitochondrial and cytoplasmic ribosomes showed major differences in the proportions of arginine, alanine and methionine. For the small subunits, arginine, aspartic acid, alanine, valine and methionine showed marked differences. We have compared these amino-acid compositions with those already published of bacterial and eukaryotic ribosomes by a statistical method of data analysis. It appeared clearly that the yeast mitoribosomes are more distant from bacterial ribosomes than from eukaryotic cytoribosomes.
已测定酿酒酵母线粒体核糖体亚基的氨基酸组成，并与细胞质核糖体亚基的氨基酸组成进行了比较。对于大亚基，线粒体核糖体和细胞质核糖体在精氨酸、丙氨酸和蛋氨酸的比例上存在主要差异。对于小亚基，精氨酸、天冬氨酸、丙氨酸、缬氨酸和蛋氨酸存在显著差异。我们通过一种统计数据分析方法，将这些氨基酸组成与已发表的细菌和真核生物核糖体的氨基酸组成进行了比较。结果清楚地表明，酵母线粒体核糖体与细菌核糖体的差异比与真核生物细胞质核糖体的差异更大。
