Protein attributes

Sequence length	347 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

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-Rule MF_00596
Catalytic activity	Inosine 5'-phosphate + NH3 + NADP+ = guanosine 5'-phosphate + NADPH. HAMAP-Rule MF_00596
Subunit structure	Homotetramer By similarity.
Sequence similarities	Belongs to the IMPDH/GMPR family. GuaC type 1 subfamily.
