CC Evidence={ECO:0000256|HAMAP-Rule:MF_01510};
CC -!- PATHWAY: Purine metabolism; GMP biosynthesis; GMP from XMP (L-Gln
CC route): step 1/1. {ECO:0000256|HAMAP-Rule:MF_01510}.
CC -!- SUBUNIT: Heterodimer composed of a glutamine amidotransferase subunit
CC (A) and a GMP-binding subunit (B). {ECO:0000256|HAMAP-Rule:MF_01510}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
