Figure 4From: Phylogeny and molecular signatures (conserved proteins and indels) that are specific for the Bacteroidetes and Chlorobi speciesPartial sequence alignments of alanyl-tRNA synthetase showing a conserved insert of about 12–14 aa that is a distinctive characteristic of Chlorobi homologs and not found in other bacteria. The dashes (-) denote identity with the amino acid on the top line. Additional abbreviations: Geo., Geobacter; Sta., Staphylococcus; Thermo., Thermoanaerobacter.Back to article page
