This is a network model of many pathways present at the neuronal synapse. The network has properties of temporal tuning as well as steady-state computational properties. In its default form the network is bistable.Bhalla US Biophys J. 2004 Aug;87(2):745-53

PKC-cytosolic acting as a Substrate in a reaction in  MAPK_network_2003 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.

1	PKC-act-by-Ca	MAPK_network_ 2003 Accession No. : 50	PKC Pathway No. : 207	0.6 (uM^-1 s^-1)	0.5 (s^-1)	Kd(bf) = 0.8333(uM)	-	Substrate Ca PKC-cytosolic Product PKC-Ca
	Need est of rate of assoc of Ca and PKC. Assume it is fast The original parameter-searched kf of 439.4 has been scaled by 1/6e8 to account for change of units to n. Kf now 8.16e-7, kb=.6085 Raised kf to 1e-6 to match Ca curve, kb to .5
2	PKC-basal-act	MAPK_network_ 2003 Accession No. : 50	PKC Pathway No. : 207	1 (s^-1)	50 (s^-1)	Keq = 50(uM)	0.02sec	Substrate PKC-cytosolic Product PKC-basal*
	Initial basal levels were set by kf = 1, kb = 20. In model, though, the basal levels of PKC activity are higher.
3	PKC-act-by-AA	MAPK_network_ 2003 Accession No. : 50	PKC Pathway No. : 207	0.0001 (uM^-1 s^-1)	0.1 (s^-1)	Kd(bf) = 833.3333(uM)	-	Substrate AA PKC-cytosolic Product PKC-AA*
	Raise kf from 1.667e-10 to 2e-10 to get better match to data.
4	PKC-n-DAG	MAPK_network_ 2003 Accession No. : 50	PKC Pathway No. : 207	0.0006 (uM^-1 s^-1)	0.1 (s^-1)	Kd(bf) = 166.6667(uM)	-	Substrate DAG PKC-cytosolic Product PKC-DAG
	kf raised 10 X based on Shinomura et al PNAS 88 5149-5153 1991 closer analysis of Shinomura et al: kf now 1e-8 (was 1.66e-8). Further tweak. To get sufficient AA synergy, increase kf to 1.5e-8 26 June 1996: Corrected DAG levels: reduce kf by 15x from 1.5e-8 to 1e-9
