Comments [?]

Function Catalyzes the phosphorylation of the position 2 hydroxy group of 4-diphosphocytidyl-2C-methyl-D-erythritol.
Catalytic activity RHEA:18437: 4-CDP-2-C-methyl-D-erythritol + ATP = 4-CDP-2-C-methyl-D-erythritol 2-phosphate + ADP + H(+)
case not <OC:Staphylococcus> and not <OC:Streptococcus>
Pathway Isoprenoid biosynthesis; isopentenyl diphosphate biosynthesis via DXP pathway; isopentenyl diphosphate from 1-deoxy-D-xylulose 5-phosphate: step 3/6.
end case
case <OC:Enterobacterales>
Subunit Homodimer.
end case
Similarity Belongs to the GHMP kinase family. IspE subfamily.

Comments In CHLPN there is a remnant of an ispE gene but which is interrupted by a probable natural frameshift (all CHLPN strains have it). It is orf CP0905
