CC   -!- FUNCTION: Catalyzes the phosphorylation of the position 2 hydroxy group
CC       of 4-diphosphocytidyl-2C-methyl-D-erythritol. {ECO:0000255|HAMAP-
CC       Rule:MF_00061}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=4-CDP-2-C-methyl-D-erythritol + ATP = 4-CDP-2-C-methyl-D-
CC         erythritol 2-phosphate + ADP + H(+); Xref=Rhea:RHEA:18437,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:57823,
CC         ChEBI:CHEBI:57919, ChEBI:CHEBI:456216; EC=2.7.1.148;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00061};
CC   -!- PATHWAY: Isoprenoid biosynthesis; isopentenyl diphosphate biosynthesis
CC       via DXP pathway; isopentenyl diphosphate from 1-deoxy-D-xylulose 5-
CC       phosphate: step 3/6. {ECO:0000255|HAMAP-Rule:MF_00061}.
CC   -!- SIMILARITY: Belongs to the GHMP kinase family. IspE subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_00061}.
