Pathwayi: L-histidine biosynthesis

This protein is involved in step 7 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), ATP phosphoribosyltransferase regulatory subunit (hisZ)
  2. Phosphoribosyl-ATP pyrophosphatase (hisE)
  3. Phosphoribosyl-AMP cyclohydrolase (hisI), Phosphoribosyl-AMP cyclohydrolase (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, glutamine amidotransferase subunit (hisH1), Imidazoleglycerol-phosphate synthase (HCH_04825), Imidazole glycerol phosphate synthase subunit HisH (hisH2)
  6. Imidazoleglycerol-phosphate dehydratase (hisB)
  7. Histidinol-phosphate aminotransferase (hisC)
  8. no protein annotated in this organism
  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.
