So far, we have modeled the production of enzymes that are capable of breaking rubber polymers, namely Lcp and RoxA. During the rubber degradation, however, no other products will be formed, only a bunch of small polymers with variable lengths. This means that, in a Michaelis-Menten fashion, our substrate and our product are the same. Then, we can ask which is the best way to model such behavior? Is Michaelis-Menten suitable? The result is partially yes, as we show below.

Figure 1- During the rubber degradation, Lcp and RoxA will break rubber polymers into smaller polymers. In a Michaelis-Menten fashion, our substrate and our product are the same. How can we solve it?
