Accession and Pathway Details

Accession Name	Accession No.	Accession Type	Pathway Link
CDK2-CyclinA_ activation_ pathway	42	Pathway	CDK2-CyclinA
In this version of the CDK2/Cyclin A complex activation there is discrepancy in the first curve which plots the binding reaction of CDK2 and Cyclin A expressed in E. coli. With the published rate constants the simulation does not match the published graph (Fig.1B) in Morris MC. et al. J Biol Chem. (2002) 277(26):23847-53.

The volume of this pool is scaled to 1/5.8 times the general volume in the model (1e-15 m^3) so that the range of fluorescent changes is 0.058 for complete consumption of the fluorophore (0.1 uM of Cdk2). The volume is therefore 0.1724e-15

CDK2cycA* acting as a Product in a reaction in  CDK2-CyclinA_activation_pathway 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.
