Protein name

RecName: Full=4-diphosphocytidyl-2-C-methyl-D-erythritol kinase; Short=CMK; EC=2.7.1.148; AltName: Full=4-(cytidine-5'-diphospho)-2-C-methyl-D-erythritol kinase;

Gene name

ispE

FUNCTION: Catalyzes the phosphorylation of the position 2 hydroxy group of 4-diphosphocytidyl-2C-methyl-D-erythritol (By similarity).

CATALYTIC ACTIVITY: ATP + 4-(cytidine 5'-diphospho)-2-C-methyl-D-erythritol = ADP + 2-phospho-4-(cytidine 5'-diphospho)-2-C-methyl-D-erythritol.

PATHWAY: Isoprenoid biosynthesis; isopentenyl diphosphate biosynthesis via DXP pathway; isopentenyl diphosphate from 1-deoxy-D-xylulose 5-phosphate: step 3/6.

SUBUNIT: Homodimer (By similarity).

SIMILARITY: Belongs to the GHMP kinase family. IspE subfamily.
