General annotation (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. HAMAP MF_00596

Catalytic activity

Inosine 5'-phosphate + NH3 + NADP+ = guanosine 5'-phosphate + NADPH. HAMAP MF_00596

Subunit structure

Homotetramer By similarity. HAMAP MF_00596

Sequence similarities

Belongs to the IMPDH/GMPR family. GuaC type 1 subfamily.
