Burkholderia contaminans Biofilm Regulating Operon and Its Distribution in Bacterial Genomes

Figure 4

ML phylogenetic trees based on aligned amino acid characters of (a) response regulator (REC signal receiver domain and trans_reg_C effector domain), (b) uncharacterized conserved protein, containing LysM and FecR domains, (c) histidine kinase PAS + HisKA + HATPase_c domains, and (d) histidine kinase CHASE2 domain. Dark blue: Burkholderiaceae, blue: Ralstoniaceae, green: Alcaligenaceae, and grey: Pseudomonas aeruginosa. 228 aligned characters of response regulator (REC signal receiver domain + trans_reg_C effector) (a), 213 and 199 aligned characters of histidine kinase (PAS + HisKA + HATPase_c and CHASE2, resp.) (b, c), and 113 aligned characters of peptidoglycan-binding protein (LysM and FecR domain) (d) were taken for phylogeny reconstruction.
