Modeling
This page contains mathematical equations using MathML. Most browsers support it (Safari, Firefox, etc.) but Chrome and IE do not. If you are using Chrome or IE, please consider viewing this page in an alternative browser.
The pathway triggering the expression of mCherry upon reception of Glucose is shown in Figure 1
Using the generalized mass action equations and the pathway shown in the figure above, we can write the kinetics of the systems in the following form:
