Proposed genetic circuit. Our circuit is composed of three well differentiated parts: 1) The OR function, with inputs A and B, inducing the expression of X and I1 by binding to their correspondent promoter; 2) The NOT function, with output I2, controlled by a constitutive promoter which is repressed by X; 3) A switch, made up of two constitutive promoters which express repressors R1 and R2 as well as the reporter Out. Protein complexes C i are formed by the sequestration of the R i by I i .
