Abstract

The nucleotide sequences of cloned genes coding for the elongation factor Tu of seven eubacteria have been determined. These genes were from Anacystis nidulans, Bacillus subtilis, Bacteroides fragilis, "Deinonema" spec., Pseudomonas cepacia, Shewanella putrefaciens and Streptococcus oralis. The primary structures of the genes were compared to the available sequences of prokaryotic elongation factors Tu and eukaryotic elongation factors 1 alpha. A conservation profile was determined for homologous amino acid residues. Sites of known or putative functions are usually located at highly conserved positions or within highly conserved sequence stretches. The aligned 24 amino acid sequences were used as basis for a phylogenetic analysis. The phylogenetic tree corroborates the kingdom as well as phylum concept deduced from 16S rRNA data.
