Accession and Pathway Details

Accession Name	Accession No.	Accession Type	Pathway Link
Osc_Ca_ IP3metabolism	32	Network	MIPP,  CaMKII,  CaM,   PKC,  IP3-3K,  Gq,   PLCbeta,  134_dephos,  145_dephos,   IP4-system,  IHP-system,  1345_dephos,   CaRegulation,  Othmer-Tang-model
This network models an oscillatory calcium response to GPCR mediated PLCbeta activation, alongwith detailed InsP3 metabolism in the neuron. It is similar to the Osc_Ca_IP3metab model (accession 24) except that some enzymes in the InsP3 metabolism network have been modified to have reversible kinetics rather than Michaelis-Menten kinetics. The modified enzymes belong to the groups: IP4-system, IP3-3K, 145_dephos and 134_dephos. Mishra J, Bhalla US. Biophys J. 2002 Sep;83(3):1298-316.

PP-IP5-K acting as a Substrate in a reaction in  Osc_Ca_IP3metabolism 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.
