Fig. 13From: Mathematical modelling of SigE regulatory network reveals new insights into bistability of mycobacterial stress responseInput–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).
