The amino acid sequence of the principal soluble cytochrome c from the phototrophic acidophilic bacterium Rhodopseudomonas (or Rhodopila) globiformis was determined. By the criteria of percentage sequence identity and fewness of internal insertions and deletions it is more similar in sequence to some mitochondrial cytochromes c than to any known bacterial cytochrome. The organism does not have any properties that commend it as being particularly similar to postulated prokaryotic precursors of the mitochondrion. We consider that the relatively high degree of sequence similarity is an instance of convergence, and is an example of the limitations that are imposed on attempts to deduce distant evolutionary relationships from sequence information. Detailed evidence for the amino acid sequence of the protein has been deposited as Supplementary Publication SUP 50136 (12 pages) at the British Library Lending Division, Boston Spa, West Yorkshire LS23 7BQ, U.K., from whom copies are available on prepayment [see Biochem. J. (1987) 241, 5].

AbstractBacterial lipids are well-preserved in ancient rocks and certain ones have been used as indicators of specific bacterial metabolisms or environmental conditions existing at the time of rock deposition. Here we show that an anaerobic bacterium produces 3-methylhopanoids, pentacyclic lipids previously detected only in aerobic bacteria and widely used as biomarkers for methane-oxidizing bacteria. Both Rhodopila globiformis, a phototrophic purple nonsulfur bacterium isolated from an acidic warm spring in Yellowstone, and a newly isolated Rhodopila species from a geochemically similar spring in Lassen Volcanic National Park (USA), synthesized 3-methylhopanoids and a suite of related hopanoids and contained the genes encoding the necessary biosynthetic enzymes. Our results show that 3-methylhopanoids can be produced under anoxic conditions and challenges the use of 3-methylhopanoids as biomarkers of oxic conditions in ancient rocks and as prima facie evidence that methanotrophic bacteria were active when the rocks were deposited.
