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_00596}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=IMP + NADP(+) + NH4(+) = GMP + 2 H(+) + NADPH;

CC   -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_00596}.
CC   -!- SIMILARITY: Belongs to the IMPDH/GMPR family. GuaC type 1 subfamily.
