Genetically modified microorganisms that have the ability to convert carbon substrates into chemical products such as 2,3-BDO; 1,4-BDO; isobutyraldehyde; isobutanol; 1-butanol; n-butanol; ethanol; fatty alcohols; and fatty acid methyl ester are disclosed. For example, genetically modified methanotrophs that are capable of generating 2,3-BDO; 1,4-BDO; isobutyraldehyde; isobutanol; 1-butanol; n-butanol; ethanol; fatty alcohols; and fatty acid methyl ester at high titers from a methane source are disclosed. Methods of making these genetically modified microorganisms and methods of using them are also disclosed. These microorganisms and methods make use of molecular switches to regulate gene expression.

The present invention relates to a cell which has been modified in comparison with its wild type in such a way that it is capable of forming more, by comparison with its wild, 3-hydroxyisobutyric acid or poly-hydroxyalkanoates based on 3-hydroxyisobutyric acid via methylmalonate-semialdehyde or 3-hydroxybutyryl-coenzyme A as precursors. The invention also relates to a method of generating a genetically modified cell, to the genetically modified cell obtainable by these methods, to a method of producing 3-hydroxyisobutyric acid or polyhydroxyalkanoates based on 3-hydroxyisobutyric acid, to a method of producing methacrylic acid or methacrylic esters, and to a method of producing polymethacrylic acid or polymethacrylic esters. The present invention furthermore relates to an isolated DNA, to a vector, to the use of this vector for transforming a cell, to a transformed cell, and to a polypeptide.
