Abstract:

Metabolic engineering allows purposeful modification of metabolic and cellular network towards achieving several goals including enhanced production of various bioproducts, production of novel products, and broadening the substrate utilization range. Traditional metabolic engineering has been performed by manipulating a handful of genes and pathways based on known literature information and our rational thinking. Advances in omics technology, computational bioscience, and systems biology are now providing us with new information and knowledge that had not been possible to obtain using traditional approaches. Systems biology is allowing us to elucidate the metabolism and physiology of cells and organisms at the global levels. Metabolic engineering based on the systems-level analysis of cells and organisms, termed systems metabolic engineering, is now offering a new powerful way of designing and developing strains having improved performance. In this lecture, I will present the general strategies of systems metabolic engineering. Also, several examples of applying systems metabolic engineering for the production of amino acids, primary metabolite (succinic acid) and secondary metabolite (lycopene) will be presented.
