Molecule Parameter List for MR

The statistics table lists the distribution of a molecule acting either as a substrate, product, enzyme or as a molecule within the network.
The text color of a molecule is highlighted by

color.

Accession and Pathway Details

Accession Name	Accession No.	Accession Type	Pathway Link
simple_AMPAR_ traff_model2	61	Network	Shared_Object_simple_AMPAR_traff_model2, Membrane, Internal
This is a highly simplified model of the AMPAR trafficking cycle that exhibits bistability. It is model 2 from Hayer and Bhalla, PLoS 2005. Its main purpose it to illustrate how the bistability arises.

MR acting as a Substrate for an Enzyme in simple_AMPAR_traff_model2 Network

Enzyme Molecule / Enzyme Activity	Accession Name	Pathway Name	Km (uM)	kcat (s^-1)	Ratio	Enzyme Type	Reagents
PKA-active / memb-PKA-act	simple_AMPAR_ traff_model2 Accession No. : 61	Shared_Object_ simple_AMPAR_ traff_model2 Pathway No. : 254	3.74995	6	4	explicit E-S complex	Substrate MR Product MR*
Note halving of Km. See notes for internal-PKA-act enzymatic step.

MR acting as a Product of an Enzyme in simple_AMPAR_traff_model2 Network

Enzyme Molecule / Enzyme Activity	Accession Name	Pathway Name	Km (uM)	kcat (s^-1)	Ratio	Enzyme Type	Reagents
PP1-active / PP1	simple_AMPAR_ traff_model2 Accession No. : 61	Membrane Pathway No. : 255	0.999989	0.35	4	explicit E-S complex	Substrate MR* Product MR
Note that Km is halved from 2 to 1, as compared to original detailed model. This is because each substrate represents two subunits of the original detailed model.

MR acting as a Substrate in a reaction in simple_AMPAR_traff_model2 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.

** This is a trasport reation between compartments of different volumes. Therefore Kd is not applicable. Please Note Kf, Kb units are in number of molecules instead of concentration
