  • Publication number: 20110008858
    Abstract: A non-naturally occurring microbial organism has at least one exogenous nucleic acid encoding a MEK pathway enzyme expressed in a sufficient amount to produce MEK. The MEK pathway includes an enzyme selected from an acetoacetyl-CoA dehydrogenase (bifunctional), an acetoacetyl-CoA aldehyde dehydrogenase, a 3-oxobutyraldehyde reductase, a 3-oxobutanol dehydratase, an MEK oxidoreductase, a 3-oxobutyraldehyde aminotransferase, a 4-aminobutan-2-one deaminase, a 2-amino-4-ketopentanoate (AKP) thiolase, an AKP aminotransferase, a 2,4-dioxopentanoate decarboxylase, an AKP deaminase, an acetylacrylate decarboxylase, an AKP decarboxylase, a glutamate dehydrogenase, a 3-oxobutyraldehyde oxidoreductase (aminating) and an AKP oxidoreductase (aminating). A 2-butanol pathway further includes an MEK reductase. A method for producing MEK or 2-butanol includes culturing these organisms under conditions and for a sufficient period of time to produce MEK or 2-butanol.
