General annotation (Comments)

Function	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. HAMAP MF_00278
Catalytic activity	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. HAMAP MF_00278
Pathway	Amino-acid biosynthesis; L-histidine biosynthesis; L-histidine from 5-phospho-alpha-D-ribose 1-diphosphate: step 5/9. HAMAP MF_00278
Subunit structure	Heterodimer of HisH and HisF By similarity. HAMAP MF_00278
Subcellular location	Cytoplasm By similarity HAMAP MF_00278.
Sequence similarities	Contains 1 glutamine amidotransferase type-1 domain.
