Figure 1.
Atrazine metabolic degradation pathway and strains used. (a) Intermediary products of the upper and lower parts of the metabolic degradation of atrazine, as well as genes associated with the different reactions are indicated. (b) The four ancestral strains, as well as their corresponding atrazine degrading gene repertoire are indicated. Genes encoding enzymes involved in the formation of N-containing by-products are coloured in blue while genes encoding enzymes involved in the formation of C-containing by-products are contoured.
