Comments

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 (By similarity).
CATALYTIC ACTIVITY: Inosine 5'-phosphate + NH₃ + NADP⁺ = guanosine 5'-phosphate + NADPH.
SUBUNIT: Homotetramer (By similarity).
SIMILARITY: Belongs to the IMPDH/GMPR family. GuaC type 1 subfamily.
