Understanding bistability in complex enzyme-driven reaction networks

Abstract: Much attention has been paid recently to bistability and switch-like behavior that might be resident in important biochemical reaction networks. There is, in fact, a great deal of subtlety in the relationship between the structure of a reaction network and its capacity to engender bistability. In common physicochemical settings, large classes of extremely complex networks, taken with mass action kinetics, cannot give rise to bistability no matter what values the rate constants take. On the other hand, bistable… Show more

“…In particular, very surprisingly the model, the derivation of which uses only the rules of enzyme kinetics, turns out not to be structurally stable in the following sense: if protein turnover is incorporated into the equations, bistability can disappear for arbitrarily small values of kinetic constants describing protein turnover. Observe, in this context, that the models of and (Craciun et al, 2006) do not take protein turnover into account.…”

“…The SR graph was first introduced in [10] for the analysis of massaction systems, inspired by the SCL graph of Schlosser and Feinberg [22,23]; see also [12,15]. The case of networks that may contain onestep catalysis is discussed in [10,12,15] for mass-action kinetics, and in [9] for general kinetics.…”

“…Also, the modelling of enzymatic reaction cascades is of interest in drug development mainly to get a better overall view of the biological processes. [29,30,31] In this paper a new method to model multi-component assays with quantitative results is presented. The method uses a network of binding complexes and nodes to calculate and simulate a chemical system.…”
