Response to nitrogen-shifts in our simulation. Blue line indicates simulated levels of cdG, GTP, and (p)ppGpp when [Gln]=10000 μM. Red line indicates simulated levels of these three molecules when glutamine changes to 100 μM at simulation time 600. Yellow line indicates the simulation when the glutamine recovers to 10000 μM. The end point of previous simulation is used to be the initial point of the following simulation at a different glutamine level
