: isopentenyl diphosphate biosynthesis via DXP pathway Pathwayi
This protein is involved in step 5 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 (ferredoxin) (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.
