| | This is not directly in the Holmes model. It is a trick used in GENESIS/Kinetikit to scale activity down for intramolecular reactions. Here it is used to scale the autophosph reactions such that only neighboring subunits will phosphorylate each other. This is done by scaling down the actual conc (in the enzyme parent, Tot-active-CaMKII) by the total conc such that instead of a conc, we the fraction of nearby subunits that will be active. Note that this conc of 10000 CaMKII subunits is 10 times the true conc, since only 1/10 of the molecules are neighboring molecules. |
