  • Use of phosphoketolase for producing useful metabolites
    Publication number: 20060040365
    Abstract: The present invention provides a bacterium which has an ability to produce a useful metabolite derived from acetyl-coenzyme A, such as L-glutamic acid, L-glutamine, L-proline, L-arginine, L-leucine, L-cysteine, succinate, and polyhydroxybutyrate, wherein said bacterium is modified so that activities of D-xylulose-5-phosphate phosphoketolase and/or fructose-6-phosphate phosphoketolase are enhanced. The present invention also provides a method for producing the useful metabolite using the bacterium.
