Comparative analysis of class activity scores across balanced growth conditions. Comparison of class activity scores across balanced growth in wild-type (blue) and NOX (yellow) conditions. The classes are sorted according to maximum difference in activities. Both conditions are characterized by relatively few positive class scores - transporters and carbon utilization related classes (highlighted in yellow) - indicating coordinated activity of these genes as a function of condition levels (growth rates). Classes active in the wild type only are highlighted in blue.
