Accession and Pathway Details

Accession Name	Accession No.	Accession Type	Pathway Link
Ajay_Bhalla_ 2007_PKM	80	Network	Shared_Object_Ajay_Bhalla_2007_PKM, PKC, MAPK, Ras, CaM, PKM
This is a non-bistable model of ERKII signaling that also incorporates PKM synthesis triggered by Ca influx. It is a simplified variant of the model of Ajay SM, Bhalla US. Eur J Neurosci. 2004 Nov;20(10):2671-80.

CaM-GEF acting as an Enzyme in Ajay_Bhalla_2007_PKM Network

Enzyme Molecule / Enzyme Activity	Accession Name	Pathway Name	Km (uM)	kcat (s^-1)	Ratio	Enzyme Type	Reagents
CaM-GEF / CaM-GEF-act-ras	Ajay_Bhalla_ 2007_PKM Accession No. : 80	Ras Pathway No. : 372	0.50505	0.2	4	explicit E-S complex	Substrate GDP-Ras Product GTP-Ras
Kinetics same as GEF-bg_act-ras, but as of March 17, 2006, the kcat is scaled from 0.02 to 0.2 to have a stronger Ca response for the direct MAPK input.

CaM-GEF acting as a Product in a reaction in Ajay_Bhalla_2007_PKM 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
CaM-bind-GEF	Ajay_Bhalla_ 2007_PKM Accession No. : 80	Ras Pathway No. : 372	199.999 (uM^-1 s^-1)	1 (s^-1)	Kd(bf) = 0.005(uM)	-	Substrate CaM-Ca4 inact-GEF Product CaM-GEF
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
