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.

Pathway: 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.
Proteins known to be involved in the 9 steps of the subpathway in this organism are:
  1. ATP phosphoribosyltransferase regulatory subunit (hisZ), ATP phosphoribosyltransferase (hisG)
  2. Phosphoribosyl-ATP pyrophosphatase (hisE)
  3. 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 subunit HisH (hisH)
  6. Imidazoleglycerol-phosphate dehydratase (hisB)
  7. Histidinol-phosphate aminotransferase 2 (hisC2), Histidinol-phosphate aminotransferase 3 (hisC3), Histidinol-phosphate aminotransferase 1 (hisC1)
  8. no protein annotated in this organism
  9. Histidinol dehydrogenase 2 (hisD2), Histidinol dehydrogenase 1 (hisD1)
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.

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 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.
