RL   Submitted (JUN-2007) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Catalyzes the NADP-dependent rearrangement and reduction of
CC       1-deoxy-D-xylulose-5-phosphate (DXP) to 2-C-methyl-D-erythritol 4-
CC       phosphate (MEP). {ECO:0000255|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         ChEBI:CHEBI:15378, ChEBI:CHEBI:57783, ChEBI:CHEBI:57792,
CC         ChEBI:CHEBI:58262, ChEBI:CHEBI:58349; EC=1.1.1.267;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00183};
CC   -!- COFACTOR:
CC       Name=a divalent metal cation; Xref=ChEBI:CHEBI:60240;
CC         Evidence={ECO:0000255|HAMAP-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:0000255|HAMAP-Rule:MF_00183}.
CC   -!- SIMILARITY: Belongs to the DXR family. {ECO:0000255|HAMAP-
CC       Rule:MF_00183}.
