L-isoleucine, one of branched chain amino acids, has been considered an industrially valuable product since it is employed as a component of pharmaceuticals, cosmetics and dietary products as well as animal feed additives. Escherichia coli, the host organism of this study, tightly regulates L-isoleucine biosynthetic pathway by operating complex regulatory mechanisms, including feedback inhibitions and transcriptional regulations. In this study, we removed all the negative regulations that hamper the production of L-isoleucine, and overexpressed the genes encoding enzymatic reactions and exporters in order to improve the host strain’s L-isoleucine-producing capability. The approaches described in this study are a good example of rationally engineering microorganisms for the enhanced production of L-isoleucine, and they can also be generally applicable to development of strains for the efficient production of other valuable bioproducts.
