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 Ci are formed by the sequestration of the Ri by Ii.
