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.
