    Abstract: A non-naturally occurring eukaryotic or prokaryotic organism includes one or more gene disruptions occurring in genes encoding enzymes imparting increased fumarate, malate or acrylate production in the organism when the gene disruption reduces an activity of the enzyme. The one or more gene disruptions confers increased production of acrylate onto the organism. Organisms that produce acrylate have an acrylate pathway that at least one exogenous nucleic acid encoding an acrylate pathway enzyme expressed in a sufficient amount to produce acrylate, the acrylate pathway comprising a decarboxylase. Methods of producing fumarate, malate or acrylate include culturing these organisms.

    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 non-natural microbial organisms containing enzymatic pathways and/or metabolic modifications for enhancing carbon flux through acetyl-CoA, or oxaloacetate and acetyl-CoA. Embodiments of the invention include microbial organisms having a pathway to acetyl-CoA and oxaloacetate that includes phosphoketolase (a PK pathway). The organisms also have either (i) a genetic modification that enhances the activity of the non-phosphotransferase system (non-PTS) for sugar uptake, and/or (ii) a genetic modification(s) to the organism's electron transport chain (ETC) that enhances efficiency of ATP production, that enhances availability of reducing equivalents or both. The microbial organisms can optionally include (iii) a genetic modification that maintains, attenuates, or eliminates the activity of a phosphotransferase system (PTS) for sugar uptake. The enhanced carbon flux through acetyl-CoA and oxaloacetate can be used for production of a bioderived compound, and the microbial organisms can further include a pathway capable of producing the bioderived compound.
