Imidazole glycerol phosphate synthase subunit HisH

Gene

hisH

Organism
Corynebacterium glutamicum (strain ATCC 13032 / DSM 20300 / JCM 1318 / LMG 3730 / NCIMB 10025)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisH subunit provides the glutamine amidotransferase activity that produces the ammonia necessary to HisF for the synthesis of IGP and AICAR (By similarity).By similarity

Catalytic activityi

5-[(5-phospho-1-deoxyribulos-1-ylamino)methylideneamino]-1-(5-phosphoribosyl)imidazole-4-carboxamide + L-glutamine = imidazole-glycerol phosphate + 5-aminoimidazol-4-carboxamide ribonucleotide + L-glutamate + H2O.

Pathwayi: L-histidine biosynthesis

This protein is involved in step 5 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 (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 (hisC)
  8. Histidinol-phosphatase (hisN)
  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.

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.
