Note halving of Km. See notes for internal-PKA-act enzyme step.
Note that Km is halved from the main model, from 7.5 to 3.75. This is because here we lump two subunits into one, thus double the effective substrate conc that the enzyme must deal with. We thank an anonymous reviewer for pointing this out.
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. This model originates from BioModels Database: A Database of Annotated Published Models (http://www.ebi.ac.uk/biomodels/).

Note halving of Km from 2 to 1. See also notes for internal-PKA-act. Basically, the enzyme must act on two substrate subunits which are lumped in the current simplification of the original detailed model. We thank an anonymous reviewer for pointing this out.
Note halving of Km. See notes for internal-PKA-act enzymatic step.
Note that Km is halved from the detailed model, as the reaction represents enzyme activity on 2 subunits.
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.
