Translational G-protein taxonomic division sequence block alignments. Structure based aligned sequences: Numbering is over total aligned set of Archaea (S. solfataricus, M. sedula, H. butylicus, M. jannaschii, and T. thermophilus) and three bacteria (G. stearothermophilus, B. halodurans, E. coli). (A) Displays the alignments for EFTu/EF1, (B) those of IF2/aeIF5b and (C) those of EFG/EF2. Light blue indicates sequence segments or universal blocks that can be aligned across both taxonomic divisions having similar secondary structures and with statistical significance; Green indicates sequence blocks alignable among and unique to Archaea, while brown indicates blocks alignable among and unique to Bacteria. These definitions are consistent with those used in Smith 2008 [1].
