Chorismate mutase (CM) and cyclohexadienyl dehydratase (CDT) catalyze two
subsequent reactions in the intracellular biosynthesis of phenylalanine. Surprisingly, exported
CMs and CDTs exist in bacterial pathogens. Here, we report the discovery of novel and
extremely rare exported bifunctional fusion enzymes, consisting of fused CM and CDT
domains. Such enzymes were found in only nine bacterial species belonging to nonpathogenic
γ- or β-proteobacteria....
