CC   -!- FUNCTION: Catalyzes the NADPH-dependent rearrangement and reduction of
CC       1-deoxy-D-xylulose-5-phosphate (DXP) to 2-C-methyl-D-erythritol 4-
CC       phosphate (MEP). {ECO:0000256|HAMAP-Rule:MF_00183}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2-C-methyl-D-erythritol 4-phosphate + NADP(+) = 1-deoxy-D-
CC         xylulose 5-phosphate + H(+) + NADPH; Xref=Rhea:RHEA:13717,

CC         Rule:MF_00183};
CC   -!- PATHWAY: Isoprenoid biosynthesis; isopentenyl diphosphate biosynthesis
CC       via DXP pathway; isopentenyl diphosphate from 1-deoxy-D-xylulose 5-
CC       phosphate: step 1/6. {ECO:0000256|ARBA:ARBA00005094, ECO:0000256|HAMAP-
CC       Rule:MF_00183}.
CC   -!- SIMILARITY: Belongs to the DXR family. {ECO:0000256|ARBA:ARBA00006825,
CC       ECO:0000256|HAMAP-Rule:MF_00183}.
CC   -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC       feature annotation. {ECO:0000256|HAMAP-Rule:MF_00183}.
