Accession Name	Accession No.	Accession Type	Pathway Link
3d_fold_model	8	Network	Shared_Object_3d_fold_model, PKC, MAPK, PLA2, Ras
This model is an annotated version of the synaptic signaling network. The primary reference is Bhalla US and Iyengar R. Science (1999) 283(5400):381-7 but several of the model pathways have been updated Bhalla US, Ram PT, Iyengar R. Science. 2002 Aug 9;297(5583):1018-23.

PKC-cytosolic acting as a Substrate in a reaction in 3d_fold_model 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.

	Name	Accession Name	Pathway Name	Kf	Kb	Kd	tau	Reagents
1	PKC-act-by-Ca	3d_fold_model Accession No. : 8	PKC Pathway No. : 55	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	3d_fold_model Accession No. : 8	PKC Pathway No. : 55	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	3d_fold_model Accession No. : 8	PKC Pathway No. : 55	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	3d_fold_model Accession No. : 8	PKC Pathway No. : 55	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
