Protein names	Recommended name:     GMP reductase     EC=1.7.1.7 Alternative name(s):     Guanosine 5'-monophosphate oxidoreductase       Short name=Guanosine monophosphate reductase
Organism	Phytophthora infestans (Potato late blight fungus)
Taxonomic identifier	4787 [NCBI]
Taxonomic lineage	Eukaryota › stramenopiles › Oomycetes › Peronosporales › Phytophthora

Protein attributes

Sequence length	362 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

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.
Catalytic activity	Inosine 5'-phosphate + NH(3) + NADP(+) = guanosine 5'-phosphate + NADPH.
Sequence similarities	Belongs to the IMPDH/GMPR family.
