    -  Comments
  • FUNCTION:Catalyzes the NADP-dependent rearrangement and reduction of 1-deoxy-D-xylulose-5-phosphate (DXP) to 2-C-methyl-D-erythritol 4-phosphate (MEP).
  • CATALYTIC ACTIVITY:2-C-methyl-D-erythritol 4-phosphate + NADP(+) = 1-deoxy-D-xylulose 5-phosphate + NADPH.
  • COFACTOR:Divalent cation. Prefers magnesium, manganese or cobalt.
  • ENZYME REGULATION:Inhibited by fosmidomycin.
  • BIOPHYSICOCHEMICAL PROPERTIES:Kinetic parameters:KM=250 uM for DXP; Note=Measured in the presence of manganese ions; pH dependence:Optimum pH is 7.0-8.5; Temperature dependence:Optimum temperature is 40-60 degrees Celsius;
  • PATHWAY:Isoprenoid biosynthesis; isopentenyl diphosphate biosynthesis via DXP pathway; isopentenyl diphosphate from 1-deoxy-D-xylulose 5-phosphate:step 1/6.
  • SUBUNIT:Homodimer.
  • SIMILARITY:Belongs to the DXR family.
