A simple model for enzyme-catalyzed reactions starts a substrate S reversibly binding with an enzyme E. Differential rate equations.
Reactions with mass action kinetics. Reactions with Henri-Michaelis-Menten kinetics.
The reactions for a single-substrate enzyme reaction mechanism see Simple Model for Single Substrate Catalyzed Reactions can be described with differential rate equations. You can enter the differential rate equations into the software as rate rules. For more information about rate rules see Rate Rules.
Determining the differential rate equations for the reactions in a model is a time-consuming process.

A better way is to enter the reactions for a single substrate enzyme reaction mechanism directly into the software. The following example using models an enzyme catalyzed reaction with mass action kinetics. The results for a simulation using reactions are identical to the results from using differential rate equations. Representing an enzyme-catalyzed reaction with mass action kinetics requires you to know the rate constants k1 , k1r , and k2.
However, these rate constants are rarely reported in the literature.
The reaction rate for a single substrate enzyme reaction using Henri-Michaelis-Menten kinetics is given below. The following example models an enzyme catalyzed reaction using Henri-Michaelis-Menten kinetics with a single reaction and reaction rate equation. Enter the reaction defined below into the software and simulate.
The results show a plot slightly different from the plot using mass action kinetics. Production of isoamyl acetate using the enzymatic synthesis method between acetic anhydride and isoamyl alcohol by having enzyme Candida antarctica Lipase B as catalyst in a solvent-free system is discussed in the third chapter. The integrated scheme with the use of the filtrate from the pretreatment of the CS and the growth conditions of Pleurotus cystidiosus is studied in the fourth chapter.
