comment
  • FUNCTION Catalyzes the acyloin condensation reaction between C atoms 2 and 3 of pyruvate and glyceraldehyde 3-phosphate to yield 1-deoxy-D-xylulose-5-phosphate (DXP). Is a limiting enzyme for plastidic isoprenoid biosynthesis and essential for chloroplast development (By similarity).CATALYTIC ACTIVITY D-glyceraldehyde 3-phosphate + pyruvate + H(+) = 1-deoxy-D-xylulose 5-phosphate + CO2COFACTOR Binds 1 Mg(2+) ion per subunit.COFACTOR Binds 1 thiamine pyrophosphate per subunit.PATHWAY Metabolic intermediate biosynthesis; 1-deoxy-D-xylulose 5-phosphate biosynthesis; 1-deoxy-D-xylulose 5-phosphate from D-glyceraldehyde 3-phosphate and pyruvate: step 1/1.SUBUNIT Homodimer.SUBCELLULAR LOCATION Belongs to the transketolase family. DXPS subfamily.
