Percentage change in the aerobic and anaerobic steady states of dependent variables X₁ (mRNA), X₂ (inactive FNR), and X₃ (active FNR) in response to percentage change in the independent variables X₄ (ClpXP), X₅ (Isc complex), and X₆ (oxygen)

	Logarithmic gains

Independent variable	X1	X2	X3	X1	X2	X3
X4	0	−0.91±0.0081	−1.8±0.016	0.011±0.0011	−0.012±0.0011	−0.024±0.0021

The mean and standard deviation for the logarithmic gains are computed with respect to the parameter sets that define the confidence intervals.

^aLogarithmic gains are not defined under anaerobic condition as X₆=0.
