design of a coenzyme A (CoA) dependent n-butanol biosynthesis pathway tailored to the metabolic physiology of the cyanobacterium Synechococcus elongatus PCC 7942 by incorporating an ATP driving force and a kinetically irreversible trap. Oxygen-sensitive CoA-acylating butyraldehyde dehydrogenase (Bldh) is exchanged for the oxygen-tolerant PduP from Salmonella enterica. Replacing Bldh with PduP in the n-butanol synthesis pathway results in n-butanol production to a cumulative titer of 404 mg/l with peak productivity of 51 mg/l per day, exceeding the base strain by 20fold.
