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 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)
  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 (CBO1807)
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.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
