CC -!- FUNCTION: Catalyzes the irreversible NADPH-dependent deamination of GMP
CC to IMP. It functions in the conversion of nucleobase, nucleoside and
CC nucleotide derivatives of G to A nucleotides, and in maintaining the
CC intracellular balance of A and G nucleotides.
CC {ECO:0000256|ARBA:ARBA00037691, ECO:0000256|HAMAP-Rule:MF_00596,
CC ECO:0000256|RuleBase:RU003929}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=IMP + NADP(+) + NH4(+) = GMP + 2 H(+) + NADPH;

CC -!- SUBUNIT: Homotetramer. {ECO:0000256|HAMAP-Rule:MF_00596}.
CC -!- SIMILARITY: Belongs to the IMPDH/GMPR family. GuaC type 1 subfamily.
CC {ECO:0000256|HAMAP-Rule:MF_00596}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00596}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
