Recombinant Salmonella paratyphi A 1-deoxy-D-xylulose-5-phosphate synthase (DXS), partial, refers to a genetically engineered version of the DXS enzyme from Salmonella paratyphi A. The DXS enzyme is crucial in the 2-C-methyl-D-erythritol 4-phosphate (MEP) pathway, which is responsible for producing isoprenoids in bacteria. Isoprenoids are essential for various cellular functions, including membrane synthesis and the production of quinones.
DXS catalyzes the first step in the MEP pathway, converting pyruvate and glyceraldehyde-3-phosphate (GAP) into 1-deoxy-D-xylulose-5-phosphate (DXP) through a transketolase-like decarboxylation reaction . This pathway is vital for the synthesis of isoprenoids, which are necessary for bacterial growth and survival.
Recombinant DXS enzymes are used in research to study the MEP pathway and its regulation. By manipulating the expression of DXS, researchers can alter the flux through the MEP pathway, affecting the production of downstream isoprenoids. This is particularly relevant in understanding bacterial metabolism and developing strategies to inhibit bacterial growth by targeting essential pathways.
