Identification
Name:4-diphosphocytidyl-2-C-methyl-D-erythritol kinase
Synonyms:
  • CMK
  • 4-(cytidine-5'-diphospho)-2-C-methyl-D-erythritol kinase
Gene Name:ispE
Enzyme Class:
Biological Properties
General Function:Involved in ATP binding
Specific Function:Catalyzes the phosphorylation of the position 2 hydroxy group of 4-diphosphocytidyl-2C-methyl-D-erythritol. Phosphorylates isopentenyl phosphate at low rates. Also acts on isopentenol, and, much less efficiently, dimethylallyl alcohol. Dimethylallyl monophosphate does not serve as a substrate
Cellular Location:Not Available
