Comments [?]

FUNCTIONCatalyzes the irreversible NADPH-dependent deamination of GMP to IMP. It functions in the conversion of nucleobase, nucleoside and nucleotide derivatives of G to A nucleotides, and in maintaining the intracellular balance of A and G nucleotides.
CATALYTIC ACTIVITY Reaction=IMP + NADP(+) + NH4(+) = GMP + 2 H(+) + NADPH; Xref=Rhea:RHEA:17185, ChEBI:CHEBI:15378, ChEBI:CHEBI:28938, ChEBI:CHEBI:57783, ChEBI:CHEBI:58053, ChEBI:CHEBI:58115, ChEBI:CHEBI:58349; EC=;
SIMILARITYBelongs to the IMPDH/GMPR family. GuaC type 2 subfamily.
