Figure 14. Sensitivity to copy number with varying internal feedback.

Sensitivity of the chemotaxis steady state to random changes in copy numbers of chemotaxis proteins under different CheB₂ feedback strengths to the cytoplasmic cluster. Sensitivity is measured as the ratio of the standard deviation of the steady state to the nominal steady state. Dashed line: Sensitivity of the chemotaxis steady state to changes in the copy number of CheA₃A₄ under different strengths of CheB₂ feedback to the cytoplasmic cluster. Solid line: Sensitivity of the chemotaxis steady state to changes in the copy number of CheY₆ under different strengths of CheB₂ feedback to the cytoplasmic cluster.
