Figure 4From: Analysis of global control of Escherichia coli carbohydrate uptakeResults of the sensitivity analysis. Black bars indicate a non-PTS substrate while white bars indicate a PTS substrate. The size of the bars represent the level of the eigenvector of the sensitivity matrix W that correspond to the maximal eigenvalue. Note, that for the non-PTS case, parameter k pts has zero sensitivity (r pts is zero in this case).Back to article page
