Journal article (other academic/artistic)abstract
- Mitochondria are thought to be derived from an ancestor of the alpha-proteobacteria and more specifically from the Rickettsiaceae. The bioenergetic repertoire of the obligate intracellular parasite Rickettsia prowazekii is consistent with its postulated r

Molecular phylogeny and rearrangement of rRNA genes in Rickettsia species

In: MOLECULAR BIOLOGY AND EVOLUTION. - : SOC MOLECULAR BIOLOGY EVOLUTION. - 0737-4038. ; 16:7, s. 987-995
-
Journal article (other academic/artistic)abstract
- 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. Rather, the 16S rR

Journal article (other academic/artistic)abstract
- The gene encoding elongation factor Tu (tuf) in aphid endosymbionts (genus Buchnera) evolves at rates of 1.3 X 10(-10) to 2.5 X 10(-10) nonsynonymous substitutions and 3.9 X 10(-9) to 8.0 X 10(-9) synonymous substitutions per position per year. These rate
