1-(5-phospho-beta-D-ribosyl)-5-((5-phospho-beta-D-ribosylamino)methylideneamino)imidazole-4-carboxamide = 5-((5-phospho-1-deoxy-D-ribulos-1-ylamino)methylideneamino)-1-(5-phospho-beta-D-ribosyl)imidazole-4-carboxamide.UniRule annotation

Pathwayi: L-histidine biosynthesis

This protein is involved in step 4 of the subpathway that synthesizes L-histidine from 5-phospho-alpha-D-ribose 1-diphosphate.UniRule annotation
Proteins known to be involved in the 9 steps of the subpathway in this organism are:
  1. ATP phosphoribosyltransferase (hisG)
  2. Histidine biosynthesis bifunctional protein HisIE (hisI)
  3. Histidine biosynthesis bifunctional protein HisIE (hisI)
  4. 1-(5-phosphoribosyl)-5-[(5-phosphoribosylamino)methylideneamino] imidazole-4-carboxamide isomerase (hisA)
  5. Imidazole glycerol phosphate synthase subunit HisF (hisF), Imidazole glycerol phosphate synthase subunit HisH (hisH)
  6. Histidine biosynthesis bifunctional protein HisB (hisB)
  7. Histidinol-phosphate aminotransferase (hisC)
  8. Histidine biosynthesis bifunctional protein HisB (hisB)
  9. Histidinol dehydrogenase (hisD)
This subpathway is part of the pathway L-histidine biosynthesis, which is itself part of Amino-acid biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-histidine from 5-phospho-alpha-D-ribose 1-diphosphate, the pathway L-histidine biosynthesis and in Amino-acid biosynthesis.
