This is the SBToolBox code we developed for simulation of the ODEs model.

The SBToolBox Code

• • • • • • • • • • MODEL NAME

Model of the Division PoPer Construct of Edinburgh iGEM 2007 Team
********** MODEL NOTES
The model represents the Division PoPper construct with the addition of a reporter protein placed downstream
********** MODEL STATES
d/dt(YFP) = YFPexp*ForwardPhase(time)-YFPdeg*YFP 
d/dt(GFP) = GFPexp*BackwardPhase(time)-GFPdeg*GFP 
YFP(0) = 0
GFP(0) = 0
********** MODEL PARAMETERS
YFPexp = 0.0001 
GFPexp = 0.0001 
GFPdeg = 0.05 
YFPdeg = 0.05
