Evolutionary relationships of OxyR and SoxR of P. xenovorans LB400 and other bacteria. Mid-rooted Bayesian Inference trees calculated by MrBayes of the OxyR and SoxR regulators with experimental evidence. P. xenovorans LB400 OxyR (PxOxyR) and SoxR (PxSoxR) are shown in bold letters and marked with a dark circle. Node values represent the bootstrapping value (%) of the analysis. Each group determined was identified at the class rank level. If the amino acid sequences within each group correspond to the same family rank, the taxon name is included in parentheses. A Phylogenetic tree of the H2O2-sensing transcriptional regulator OxyR homologs. Four major groups were identified, predominantly clustered by taxonomic relatedness. PxOxyR is encompassed within the Group IA, represented by Burkholderiales. B Phylogenetic tree of the redox-sensitive transcriptional regulator SoxR homologs. Four major groups are identified, including three singleton sequences, not observing a clear taxonomic distribution within the groups. PxSoxR is a singleton closer to the SoxR regulator of Chromobacterium violaceum DSM 30191 than to other groups
