Phylogenetic trees of the α subunits (a), β subunits (b), and reductases (c) of known and putative class IB DOs. Also included were two α subunit components from different ARHDO classes (Table 1): NDO (NdoB, class III, M23914 [27]) and phthalate DO (Pht3, class IA, D13229 [34]). An outgroup (Pht3) was used only for panel a. Abbreviations: Abs, 2-aminobenzenesulfonate DO of Alcaligenes sp. strain AF109074) (29); Ant, AntDO of Acinetobacter sp. strain ADP1 (6); Ant(Pa), putative sequence of P. aeruginosa PAO1; Ben, BenDO of Acinetobacter sp. strain ADP1 (32); Ben(Pa), putative sequence of P. aeruginosa PAO1; Ben(Pp), sequence of P. putida PRS2000 (8); Cbd, 2-halobenzoate 1,2-DO of B. cepacia (X79076 [16]); Tft, 2,4,5-trichlorophenoxyacetic acid oxygenase of B. cepacia (U11420 [9]); Xyl, toluate 1,2-DO of P. putida (PIR A41659 [17]). The numbers at branch points indicate the confidence (in percent) as determined by bootstrap analysis with 100 replicates. The scale bar indicates the relative phylogenetic distances measured as number of amino acid substitutions per site.
