Identifier
GUAC
Protein name
RecName: Full=GMP reductase;
EC 1.7.1.7;
AltName: Full=Guanosine 5'-monophosphate oxidoreductase;
Short=Guanosine monophosphate reductase;
Gene name
guaC

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.
Catalytic activity RHEA:17185: IMP + NADP(+) + NH4(+) = GMP + 2 H(+) + NADPH
EC 1.7.1.7
Subunit Homotetramer.
Similarity Belongs to the IMPDH/GMPR family. GuaC type 1 subfamily.
