    Abstract: The invention provides a non-naturally occurring microbial organism having a 2-hydroxyisobutyric acid, 3-hydroxyisobutyric acid or methacrylic acid pathway. The microbial organism contains at least one exogenous nucleic acid encoding an enzyme in a 2-hydroxyisobutyric acid, 3-hydroxyisobutyric acid or methacrylic acid pathway. The invention additionally provides a method for producing 2-hydroxyisobutyric acid, 3-hydroxyisobutyric acid or methacrylic acid. The method can include culturing a 2-hydroxyisobutyric acid, 3-hydroxyisobutyric acid or methacrylic acid producing microbial organism expressing at least one exogenous nucleic acid encoding a 2-hydroxyisobutyric acid, 3-hydroxyisobutyric acid or methacrylic acid pathway enzyme in a sufficient amount and culturing under conditions and for a sufficient period of time to produce 2-hydroxyisobutyric acid, 3-hydroxyisobutyric acid or methacrylic acid.

    Abstract: The invention provides a non-naturally occurring microbial organism having a 6-aminocaproic acid, caprolactam, hexametheylenediamine or levulinic acid pathway. The microbial organism contains at least one exogenous nucleic acid encoding an enzyme in the respective 6-aminocaproic acid, caprolactam, hexametheylenediamine or levulinic acid pathway. The invention additionally provides a method for producing 6-aminocaproic acid, caprolactam, hexametheylenediamine or levulinic acid. The method can include culturing a 6-aminocaproic acid, caprolactam or hexametheylenediamine producing microbial organism, where the microbial organism expresses at least one exogenous nucleic acid encoding a 6-aminocaproic acid, caprolactam, hexametheylenediamine or levulinic acid pathway enzyme in a sufficient amount to produce the respective product, under conditions and for a sufficient period of time to produce 6-aminocaproic acid, caprolactam, hexametheylenediamine or levulinic acid.

    Abstract: The invention provides a non-naturally occurring microbial biocatalyst including a microbial organism having a 4-hydroxybutanoic acid (4-HB) biosynthetic pathway having at least one exogenous nucleic acid encoding 4-hydroxybutanoate dehydrogenase, succinyl-CoA synthetase, CoA-dependent succinic semialdehyde dehydrogenase, or α-ketoglutarate decarboxylase, wherein the exogenous nucleic acid is expressed in sufficient amounts to produce monomeric 4-hydroxybutanoic acid (4-HB). Also provided is a non-naturally occurring microbial biocatalyst including a microbial organism having 4-hydroxybutanoic acid (4-HB) and 1,4-butanediol (BDO) biosynthetic pathways, the pathways include at least one exogenous nucleic acid encoding 4-hydroxybutanoate dehydrogenase, succinyl-CoA synthetase, CoA-dependent succinic semialdehyde dehydrogenase, 4-hydroxybutyrate:CoA transferase, 4-butyrate kinase, phosphotransbutyrylase, α-ketoglutarate decarboxylase, aldehyde dehydrogenase, alcohol dehydrogenase or an aldehyde/alcohol dehydrogenase, wherein the exogenous nucleic acid is expressed in sufficient amounts to produce 1,4-butanediol (BDO). Additionally provided is a method for the production of 4-HB. The method includes culturing a non-naturally occurring microbial organism having a 4-hydroxybutanoic acid (4-HB) biosynthetic pathway including at least one exogenous nucleic acid encoding 4-hydroxybutanoate dehydrogenase, succinyl-CoA synthetase, CoA-dependent succinic semialdehyde dehydrogenase or α-ketoglutarate decarboxylase under substantially anaerobic conditions for a sufficient period of time to produce monomeric 4-hydroxybutanoic acid (4-HB). Further provided is a method for the production of BDO. The method includes culturing a non-naturally occurring microbial biocatalyst, comprising a microbial organism having 4-hydroxybutanoic acid (4-HB) and 1,4-butanediol (BDO) biosynthetic pathways, the pathways including at least one exogenous nucleic acid encoding 4-hydroxybutanoate dehydrogenase, succinyl-CoA synthetase, CoA-dependent succinic semialdehyde dehydrogenase, 4-hydroxybutyrate:CoA transferase, 4-hydroxybutyrate kinase, phosphotranshydroxybutyrylase, α-ketoglutarate decarboxylase, aldehyde dehydrogenase, alcohol dehydrogenase or an aldehyde/alcohol dehydrogenase for a sufficient period of time to produce 1,4-butanediol (BDO). The 4-HB and/or BDO products can be secreted into the culture medium.
