CC -!- FUNCTION: IGPS catalyzes the conversion of PRFAR and glutamine to IGP,
CC AICAR and glutamate. The glutaminase domain produces the ammonia
CC necessary for the cyclase domain to produce IGP and AICAR from PRFAR.
CC The ammonia is channeled to the active site of the cyclase domain.
CC {ECO:0000256|PIRNR:PIRNR036936}.
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 ECO:0000256|PIRNR:PIRNR036936};
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|PIRNR:PIRNR036936}.
CC -!- SIMILARITY: Belongs to the HisA/HisF family.
CC {ECO:0000256|RuleBase:RU003657}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the HisA/HisF family.
