== Function ==
==Reference==
[https://www.uniprot.org/uniprot/HIS6_THEMA HIS6_THEMA] IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisF subunit catalyzes the cyclization activity that produces IGP and AICAR from PRFAR using the ammonia provided by the HisH subunit.[HAMAP-Rule:MF_01013]
