Strain engineering for proline involves the fine-tuning of several genetic and metabolic elements within the host organism. By strategically altering gene expression, enzyme activity, and cellular regulation, it is possible to increase the efficiency of proline production significantly. This is achieved by optimizing key metabolic steps involved in the glutamate-to-proline pathway, ultimately resulting in elevated proline yields.
