Fig. 4From: Resource constrained flux balance analysis predicts selective pressure on the global structure of metabolic networksStructural parameters for the toy-model. a Growth rate for different switching parameters, r. Two discontinuities exist in the slope of the curve at r=0.25 and r=0.5. b Pathway length vs. r. c Number of nodes vs. r. d Number of reactions vs. r. Structural parameters of the optimized network confirm that only r=0.25 is a structural transitionBack to article page
