Figure 1.

Schematic representation of aromatic peripheral and central catabolic pathways/reactions present in C. metallidurans CH34. The inner circle (yellow) includes ring cleavage product structures of aromatic central catabolic pathways. The outer circle (blue) includes the structure of dihydroxylated and aryl-CoA ring cleavage intermediates. Dashed arrows indicate multiple steps. Red arrows represent enzymes not encountered in C. metallidurans CH34 genome. Bacterial growth was observed on peripheral compounds marked with a green dot as the only carbon and energy source.
