This is the complete model of CaMKII bistability, model 3. It exhibits bistability in CaMKII activation due to autophosphorylation at the PSD and local saturation of PP1. This version of model 3 includes PKA regulatory input. This has little effect on the deterministic calculations, but the PKA pathway introduces a lot of noise which causes a difference in stochastic runs.

NMDAR acting as a Molecule in  CaMKII_model3 Network

The stochiometry is a bit off here. Each NMDAR actually binds to a holoenzyme, about 12 CaMKII subunits. But our CaMKII calculations are in terms of individual subunits. So as a hack, we put in much more NMDAR than is actually there.

NMDAR acting as a Substrate in a reaction in  CaMKII_model3 Network

Kd is calculated only for second order reactions, like nA+nB <->nC or nA<->nC+nD, where n is number and A,B,C,D are molecules, where as for first order reactions Keq is calculated. Kd for higher order reaction are not consider.
