             <p>We will tune the model to identify synthetic targets that can enhance 5-ALA. When comparing the differences in protein requirements between the cell growth stage and the product synthesis stage, 30 proteins were identified as the most demanded proteins that needed to be upregulated. While 10 proteins are classified as having reduced demand and need to be downgraded. </p >
