酿酒酵母线粒体蛋白转运系统在立克次体中的同源分析

四川大学学报. 自然科学版, 2011
进化分析表明,与线粒体亲缘关系最近的原核生物是立克次体(Rickettsia prowazekii).搜索酿酒酵母(Saccharomyces cerevisia)线粒体蛋白转运系统的35个亚基在立克次体中的同源蛋白质,仅发现了5个同源蛋白,且它们只属于转运系统在线粒体外膜和基质上的模块,没有发现转运系统在膜间隙和内膜模块的同源蛋白.对大肠杆菌(Escherichiacoli K-12 MG1655)的分析也有类似的结果.因此线粒体蛋白转运系统应该不是直接起源于内共生的原核生物.

Molecular phylogeny and rearrangement of rRNA genes in Rickettsia species

, 1999
It has previously been observed that Rickettsia prowazekii has an unusual arrangement of the rRNA genes. In this species, the three rRNA genes, 16S (rrs), 23S (rrl), and 5S (rrf), are not linked in the typical arrangements for bacteria.

Pseudogenes, junk DNA, and the dynamics of Rickettsia genomes

, 2001
Studies of neutrally evolving sequences suggest that differences in eukaryotic genome sizes result from different rates of DNA loss. However, very few pseudogenes have been identified in microbial species, and the processes whereby genes and genomes ...
