CaM-GEF acting as a Product in a reaction in  Ajay_Bhalla_2004_PKM_MKP3_Tuning 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.

We have no numbers for this. It is probably between the two extremes represented by the CaMKII phosph states, and I have used guesses based on this. kf=1e-4 kb=1 The reaction is based on Farnsworth et al Nature 376 524-527 1995 2 Aug 2004 Raised Kf from 60 to 200 to achieve higher MAPK activation following Ca stimulus for PKM models. 3 Aug 2004. Lowered Kf to 100.
