Metabolism, the intricate web of biochemical reactions that sustain life within cells, serves as the powerhouse driving essential cellular functions. At the heart of metabolism lies the provision of energy and building blocks crucial for the synthesis of macromolecules, vital for cellular structures, growth, and proliferation. This complex network comprises thousands of reactions catalysed by enzymes, involving an array of co-factors and metabolites.

Traditionally, the study of metabolism has been challenging, with a predominant focus on specific pathways, enzymes, and metabolites. However, a paradigm shift has emerged through the application of engineering principles, particularly mathematical modelling, to comprehensively analyse and manipulate metabolic processes. This innovative approach not only yields profound insights into fundamental biological mechanisms but also unlocks a myriad of applications in biotechnology.

In a recent article published in QRB Discovery, the history and basic tenets of engineering metabolism are elucidated, alongside the latest advancements in the field. By harnessing the principles of metabolic engineering, researchers can design and construct novel metabolic features with diverse applications. Three key areas showcasing the transformative potential of engineering metabolism include:
