Maximum-likelihood tree based on the contatenatation of 1322 protein sequences showing the phylogenetic relationship of type strains belonging to the genus Porphyrobacter. Bootstrap values are based on 100 replicates. Bar, 0.1 substitutions per amino acid position. Red branch shows the clade within P. cryptus DSM 12079T. Altererythrobacter epoxidivorans CGMCC 1.7731T was used as an outgroup (not shown)
