Natl. Acad. Sci. U.S.A. 101:9786-9791(2004). CC -!- FUNCTION: IGPS catalyzes the conversion of PRFAR and glutamine to CC IGP, AICAR and glutamate. The HisH subunit provides the glutamine CC amidotransferase activity that produces the ammonia necessary to CC HisF for the synthesis of IGP and AICAR (By similarity). CC -!- CATALYTIC ACTIVITY: 5-[(5-phospho-1-deoxyribulos-1- CC ylamino)methylideneamino]-1-(5-phosphoribosyl)imidazole-4- CC carboxamide + L-glutamine = imidazole-glycerol phosphate + 5- CC aminoimidazol-4-carboxamide ribonucleotide + L-glutamate + H(2)O. CC -!- PATHWAY: Amino-acid biosynthesis; L-histidine biosynthesis; L- CC histidine from 5-phospho-alpha-D-ribose 1-diphosphate: step 5/9. CC -!- SUBUNIT: Heterodimer of HisH and HisF (By similarity). CC -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity). CC -!- SIMILARITY: Contains 1 glutamine amidotransferase type-1 domain.
