Gram-negative bacteria display mercury resistance conferred by the plasmid encoded mer operon. A genetic regulatory circuit (GRC), inducible by the presence of mercury compounds in the environment, allows controlling the expression of at least 6-7 mer genes producing enzymes responsible for the mercuric ions transport and reduction. In spite of extensive studies on bacterial toxic metal resistance, few and rather unstructured kinetic models have been proposed to characterize the process dynamics. This paper aims at proposing an extended dynamic model, of modular construction, to reproduce the characteristics of GRC controlling the mercury uptake and reduction process. The illustrated case study uses experimental data from literature collect...
