Metabolic engineering is a field of biotechnology that involves redesigning metabolic pathways in microorganisms, plants, or other organisms to produce valuable chemicals, fuels, pharmaceuticals, or other products. By manipulating the genetic makeup of these organisms, researchers aim to improve their ability to produce desired compounds efficiently and at high yields. This can involve optimizing enzyme pathways, introducing new pathways, or modifying existing pathways to achieve the desired metabolic outcome. Metabolic engineering has applications in a wide range of industries, including biopharmaceuticals, biofuels, agriculture, and environmental remediation.
