This is a two variable reduction of the larger 6-
variable model published in the same paper.The published equations are u'=
k4(v-u)(alpha+u^2)-k6*u, v'=Kappa-k6*
u. In the present implementation,
the change of variables z=v-u is made,
so that the system becomes the more symmetric system u'=
k4*z*(alpha+u^2)-k6*u, z'=Kappa-z*(alpha+u^2)
. The variables can be interpreted as follows:
u=[activeMPF]/[CT], v=([cyclin]+[preMPF]+[activeMPF])/[CT], z=([
cyclin]+[preMPF])/[CT], where [CT]=[CDC2]+{CDC2P]+[preMPF]+[aMPF]. |
