An exemplary non-naturally occurring microbial organism having an isopropanol pathway includes at least one exogenous nucleic acid encoding an isopropanol pathway enzyme expressed in a sufficient amount to produce isopropanol and includes a succinyl-CoA:3-ketoacid-CoA transferase. Another organism having a 4-hydroxybutryate pathway includes at least one exogenous nucleic acid including an acetoacetyl-CoA thiolase, a 3-hydroxybutyryl-CoA dehydrogenase, a crotonase, a crotonyl-CoA hydratase, a 4-hydroxybutyryl-CoA transferase, a phosphotrans-4-hydroxybutyrylase, and a 4-hydroxybutyrate kinase. An exemplary organism having a 1,4-butanediol pathway includes an acetoacetyl-CoA thiolase, a 3-Hydroxybutyryl-CoA dehydrogenase, a crotonase, a crotonyl-CoA hydratase, a 4-hydroxybutyryl-CoA reductase (alcohol forming), a 4-hydroxybutyryl-CoA reductase (aldehyde forming), and a 1,4-butanediol dehydrogenase. Such an organism further comprising an acetyl-CoA pathway. Any of the aforementioned organisms are cultured to produce isopropanol, 4-hydroxybutryate, or 1,4- butanediol. |
