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:0000256|ARBA:ARBA00025475,
CC ECO:0000256|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 Xref=Rhea:RHEA:24793, ChEBI:CHEBI:15378, ChEBI:CHEBI:29985,
CC ChEBI:CHEBI:58278, ChEBI:CHEBI:58359, ChEBI:CHEBI:58475,
CC ChEBI:CHEBI:58525; EC=4.3.2.10;
CC Evidence={ECO:0000256|ARBA:ARBA00000619, ECO:0000256|HAMAP-
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:0000256|ARBA:ARBA00005091, ECO:0000256|HAMAP-Rule:MF_01013}.
CC -!- SUBUNIT: Heterodimer of HisH and HisF. {ECO:0000256|ARBA:ARBA00011152,
CC ECO:0000256|HAMAP-Rule:MF_01013}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01013}.
CC -!- SIMILARITY: Belongs to the HisA/HisF family.
CC {ECO:0000256|ARBA:ARBA00009667, ECO:0000256|HAMAP-Rule:MF_01013,
CC ECO:0000256|RuleBase:RU003657}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
