An exponential decay model was fitted to the experimental data set of GAP degradation at 70C. The model is uploaded as an SBML file. A data file showing the model fit to the experimental data set is included. The rate constant for GAP degradation at 70C was estimated to be 0.056 1/min, equivalent to a half life time of 12.4 min.
