The structure of the noise controller. In the conventional control mechanism, the final output (X2) produces one of the controller proteins (Z1), and this protein is eliminated together with another controller protein (Z2), which generates the system’s input (X1). The Noise Controller (NC) has a nearly analogous structure, but with one key difference: the controller protein (Z4) is produced through a dimerization reaction of the final output, and this protein directly degrades the system’s input. This allowed us to derive the mathematical formula of the noise in stochastic molecular processes.
