Evolution of Lysine Biosynthesis in the Phylum Deinococcus-Thermus

Phylogenetic relationship between Deinococcus proteolyticus diaminopimelate decarboxylase and related proteins. Multiple alignment was obtained using the top 20 amino acid sequences of the BLASTp search result for D. proteolyticus diaminopimelate decarboxylase (Deipro 1375), as based on the Kyoto Encyclopedia of Genes and Genomes (KEGG) database. The maximum-likelihood tree was constructed using MEGA software version 5 [12]. The WAG model was used as the amino acid substitution model. The nearest neighbor interchange was used for the maximum-likelihood heuristic method. The γ-distributed rate was considered, and the number of discrete γ categories was 3. Bootstrap analysis was performed with 100 replicates. Red indicates D. proteolyticus.
