Input–output relationship for Module 2. (a) Block diagram. (b) Nullclines associated to the subsystem composed of ODEs (5)–(14). The blue thick line represents the amount of total SigE as a function of free SigE (reported on the x-axis). Total SigE concentration has been computed as the summation of free SigE (dashed red line) and complexes in which SigE is bounded by RseA and/or ClpC1P2 (various colours and traits).
