  • Publication number: 20040265980
    Abstract: The present invention provides methods of converting or increasing conversion of a fatty acid to its corresponding dicarboxylic acid. The methods comprise isolating a promoter from a yeast gene which gene is induced when the yeast is grown on a fatty acid or alkane substrate, and operably linking the promoter to a gene involved in dicarboxylic acid production to form an expression vector. Yeast cells are subsequently transformed with such an expression vector and cultured in a media containing an organic substrate biooxidizable to a mono- or polycarboxylic acid, and resultant yeast cells convert or increase conversion of fatty acids to their corresponding dicarboxylic acids. Examples of promoters that may be used in the methods of the present invention include those from C. tropicalis catalase, citrate synthase, 3-ketoacyl-CoA thiolase A, citrate synthase, O-acetylhomserine sulphydrylase, protease, carnitine O-acetyltransferase, hydratase-dehydrogenase, and epimerase genes.
