CC   -!- FUNCTION: IGPS catalyzes the conversion of PRFAR and glutamine to IGP,
CC       AICAR and glutamate. The HisF subunit catalyzes the cyclization
CC       activity that produces IGP and AICAR from PRFAR using the ammonia
CC       provided by the HisH subunit. {ECO:0000255|HAMAP-Rule:MF_01013}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=5-[(5-phospho-1-deoxy-D-ribulos-1-ylimino)methylamino]-1-(5-
CC         phospho-beta-D-ribosyl)imidazole-4-carboxamide + L-glutamine = 5-
CC         amino-1-(5-phospho-beta-D-ribosyl)imidazole-4-carboxamide + D-
CC         erythro-1-(imidazol-4-yl)glycerol 3-phosphate + H(+) + L-glutamate;

CC         Rule:MF_01013};
CC   -!- PATHWAY: Amino-acid biosynthesis; L-histidine biosynthesis; L-histidine
CC       from 5-phospho-alpha-D-ribose 1-diphosphate: step 5/9.
CC       {ECO:0000255|HAMAP-Rule:MF_01013}.
CC   -!- SUBUNIT: Heterodimer of HisH and HisF. {ECO:0000255|HAMAP-
CC       Rule:MF_01013}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01013}.
CC   -!- SIMILARITY: Belongs to the HisA/HisF family. {ECO:0000255|HAMAP-
CC       Rule:MF_01013}.
