Functioni

Catalyzes the formation of 4-diphosphocytidyl-2-C-methyl-D-erythritol from CTP and 2-C-methyl-D-erythritol 4-phosphate (MEP).UniRule annotationSAAS annotation

Catalytic activityi

CTP + 2-C-methyl-D-erythritol 4-phosphate = diphosphate + 4-(cytidine 5'-diphospho)-2-C-methyl-D-erythritol.UniRule annotationSAAS annotation

Pathwayi: isopentenyl diphosphate biosynthesis via DXP pathway

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