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. {ECO:0000255|HAMAP-
CC Rule:MF_03195}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=IMP + NADP(+) + NH4(+) = GMP + 2 H(+) + NADPH;
CC Xref=Rhea:RHEA:17185, ChEBI:CHEBI:15378, ChEBI:CHEBI:28938,

CC -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_03195}.
CC -!- SIMILARITY: Belongs to the IMPDH/GMPR family. GuaC type 1 subfamily.
