Production of Glucaric Acid from a Synthetic Pathway in

A synthetic pathway has been constructed for the production of glucuronic and glucaric acids from glucose in Escherichia coli Coexpression of the genes encoding myo -inositol-1-phosphate synthase (Ino1) from Saccharomyces cerevisiae and myo -inositol oxygenase (MIOX) from mice led to production of glucuronic acid through the intermediate myo -inositol
