A KINETIC MODEL IN MATLAB
How did we build it???
Using the SimBiology toolbox for MATLAB we created a framework of the enzyme kinetic modelling(Figure 1).
HRP + H2O2 → ES1 (HRP compound I) + MG → ES2(MGox +HRP compound II)
After creating the basic framework for the model we needed to create mathematical equations for each reaction with appropriate rate constants. These equations and the corresponding values are shown below in Tables 1 and 2.
Reaction Name: |
Reaction Scheme: |
Reaction Rate: |
oxidation reaction |
H2O2 + HRP -> ES1 |
k1*H2O2*HRP |
decolourization reaction |
ES1 + MG -> ES2 |
k2*ES1*MG |

ES2 (MGox +LiP compound II) |
dES2/dt = k2[ES1][S2] – k2r[ES2] |
Table3: Differential equations of reactions.
What did it show???
Before running the model we needed to decide what an appropriate endpoint of reaction would be. Therefore, concentrations of species were determined from the literature and necessary assumptions were made to check our cascade reactions work correctly.
According to chosen references points, we were trying to determine how quickly we could get a decolourization. Decolourization depends on final [ES2] (MGox +HRP compound II) concentration and degradation of MB.
Decolourization starts in 40 minutes.

What did it show???

Decolourization starts in 40 minutes.
Future plans
The most important results that we were able to achieve were the correlation between the functional assays the modelling results of our MATLAB kinetic model. In the modelling, the decolourizations start at the approximately 40 minutes while these are 60 minutes for the assay. These differences were due to the consideration of the used HRP and LIP enzymes in the modelling as purified allowing more direct interaction in between the hydrogen peroxide and the dyes. The assay was not conducted with purified enzymes but with lysate acquired from liquid culture containing impurities which slow down the conduction of the reaction. In the future, we hope to extract the enzymes from the bacteria to allow the direct contact of the enzymes and the dyes to increase spontaneity.
