FUNCTION:Catalyzes 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:Inosine 5'-phosphate + NH(3) + NADP(+) = guanosine 5'-phosphate + NADPH.
SUBUNIT:Homotetramer.
SIMILARITY:Belongs to the IMPDH/GMPR family. GuaC subfamily 1.
