Protein
2-C-methyl-D-erythritol 2,4-cyclodiphosphate synthase
Gene
ispF
Organism
Escherichia coli O45:K1 (strain S88 / ExPEC)
Status
Functioni
Involved in the biosynthesis of isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP), two major building blocks of isoprenoid compounds. Catalyzes the conversion of 4-diphosphocytidyl-2-C-methyl-D-erythritol 2-phosphate (CDP-ME2P) to 2-C-methyl-D-erythritol 2,4-cyclodiphosphate (ME-CPP) with a corresponding release of cytidine 5-monophosphate (CMP).UniRule annotation

: isopentenyl diphosphate biosynthesis via DXP pathway Pathwayi
This protein is involved in step 4 of the subpathway that synthesizes isopentenyl diphosphate from 1-deoxy-D-xylulose 5-phosphate.UniRule annotationProteins known to be involved in the 6 steps of the subpathway in this organism are:
- 1-deoxy-D-xylulose 5-phosphate reductoisomerase (dxr)
- 2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase (ispD)
- 4-diphosphocytidyl-2-C-methyl-D-erythritol kinase (ispE)
- 2-C-methyl-D-erythritol 2,4-cyclodiphosphate synthase (ispF)
- 4-hydroxy-3-methylbut-2-en-1-yl diphosphate synthase (flavodoxin) (ispG)
- 4-hydroxy-3-methylbut-2-enyl diphosphate reductase (ispH)
View all proteins of this organism that are known to be involved in the subpathway that synthesizes isopentenyl diphosphate from 1-deoxy-D-xylulose 5-phosphate, the pathway isopentenyl diphosphate biosynthesis via DXP pathway and in Isoprenoid biosynthesis.
