CC -!- FUNCTION: IGPS catalyzes the conversion of PRFAR and glutamine to IGP,
CC AICAR and glutamate. The HisH subunit catalyzes the hydrolysis of
CC glutamine to glutamate and ammonia as part of the synthesis of IGP and
CC AICAR. The resulting ammonia molecule is channeled to the active site
CC of HisF. {ECO:0000255|HAMAP-Rule:MF_00278}.
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 Evidence={ECO:0000255|HAMAP-Rule:MF_00278};
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_00278}.
CC -!- SUBUNIT: Heterodimer of HisH and HisF. {ECO:0000255|HAMAP-
CC Rule:MF_00278}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00278}.
