BenM responds to benzoate and its catabolite cis,cis-muconate. BenM activates the expression of genes coding for BenABC, BenD, and CatA, the enzymes that convert benzoate to muconate. The degradation of muconate to tricarboxylic acid cycle intermediates enables benzoate to serve as a sole carbon source for strain ADP1 (7).
