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

  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. no protein annotated in this organism

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.
