Abstract

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].
