    • The invention provides a non-naturally occurring microbial organism having a methacrylic acid, methacrylate ester, 3-hydroxyisobutyrate and/or 2-hydroxyisobutyrate pathway. The microbial organism contains at least one exogenous nucleic acid encoding an enzyme in a methacrylic acid pathway. The invention additionally provides a method for producing methacrylic acid, methacrylate ester, 3-hydroxyisobutyrate and/or 2- hydroxyisobutyrate. The method can include culturing methacrylic acid, methacrylate ester, 3-hydroxyisobutyrate and/or 2-hydroxyisobutyrate producing microbial organism, where the microbial organism expresses at least one exogenous nucleic acid encoding a methacrylic acid pathway enzyme in a sufficient amount to produce methacrylic acid, methacrylate ester, 3-hydroxyisobutyrate and/or 2-hydroxyisobutyrate, under conditions and for a sufficient period of time to produce methacrylic acid, methacrylate ester, 3-hydroxyisobutyrate and/or 2-hydroxyisobutyrate.

    • A non-naturally occurring microbial organism includes a microbial organism having a reductive TCA or Wood-Ljungdahl pathway in which at least one exogenous nucleic acid encoding these pathway enzymes is expressed in a sufficient amount to enhance carbon flux through acetyl-CoA. A method for enhancing carbon flux through acetyl-CoA includes culturing theses non-naturally occurring microbial organisms under conditions and for a sufficient period of time to produce a product having acetyl-CoA as a precursor. Another non-naturally occurring microbial organism includes at least one exogenous nucleic acid encoding an enzyme expressed in a sufficient amount to enhance the availability of reducing equivalents in the presence of carbon monoxide or hydrogen, thereby increasing the yield of redox-limited products via carbohydrate-based carbon feedstock. A method for enhancing the availability of reducing equivalents in the presence of carbon monoxide or hydrogen includes culturing this organism for a sufficient period of time to produce a product.
    • 非天然存在的微生物体包括具有还原性TCA或Wood-Ljungdahl途径的微生物生物体,其中至少一种编码这些途径酶的外源核酸以足够的量表达以增强通过乙酰辅酶A的碳通量。 通过乙酰辅酶A增强碳通量的方法包括在条件和足够的时间内培养这些非天然存在的微生物,以产生具有乙酰辅酶A作为前体的产物。 另一种非天然存在的微生物生物体包括至少一种编码以足够量表达的酶的外源核酸,以增强在一氧化碳或氢气存在下还原当量的可用性,从而通过碳水化合物 - 碳原料。 在一氧化碳或氢气存在下增强还原当量的可用性的方法包括在足够的时间内培养该生物体以产生产物。
