FIG. 2.

Organization of sequenced genes from Acidovorax strain NA3 aligned to homologous genes from Alcaligenes faecalis AFK2 (GenBank accession number AB024945), Pseudomonas putida G7 (AB237655), and Burkholderia sp. strain RP007 (AF061751). Letters indicate the gene designations for each PAH degradation operon (gst, glutathione S-transferase). Numbered or shaded ORFs are presumably unaffiliated with PAH degradation. Sequenced ORFs for NA3 are shown with solid arrows, while segments of genes for which the complete sequence was not obtained are indicated with dashed lines. Unsequenced areas of the NA3 operon lack a horizontal line. Operons were aligned by the RHD large subunit (Ac).
