Engineering New‐to‐Nature Biological Pathways for β,γ‐Alkanediol Synthesis
Advanced Science, EarlyView.β,γ‐Alkanediols are value‐added chemicals to be used as functional solvents, biofuels, and cosmetic components. This work demonstrates a carboligation‐mediated approach for synthesis of linear chain β,γ‐alkanediols in Escherichia coli, namely, hexane‐2,3‐diol (2,3‐HDO) and pentane‐2,3‐diol (2,3‐PDO). The engineered E. coli cells produce 152.2 mm (17.98
