Previously we have identified the rplA gene encoding ribosomal protein L1 in Streptomyces aureofaciens. Sequence comparison of ribosomal protein L1 among several bacterial genera revealed a high level of conservation. Based on this conservation, these proteins were used as a phylogenetic tool to compare evolutionary relationships among eubacteria and archaebacteria. This phylogenetic analysis of L1 ribosomal proteins including the S. aureofaciens rplA gene product revealed, except similar bacterial groupings, some new evolutionary relationships.
此前我们已在金色链霉菌中鉴定出编码核糖体蛋白L1的rplA基因。对几个细菌属中的核糖体蛋白L1进行序列比较后发现其具有高度保守性。基于这种保守性，这些蛋白被用作一种系统发育工具来比较真细菌和古细菌之间的进化关系。对包括金色链霉菌rplA基因产物在内的L1核糖体蛋白进行的系统发育分析揭示，除了相似的细菌分组外，还存在一些新的进化关系。
