    -  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:Inosine 5'-phosphate + NH(3) + NADP(+) = guanosine 5'-phosphate + NADPH.
  • SUBUNIT:Homotetramer.
  • INTERACTION:P76015:dhaK; NbExp=1; IntAct=EBI-544491, EBI-544485; P15034:pepP; NbExp=2; IntAct=EBI-544491, EBI-554801;
  • SIMILARITY:Belongs to the IMPDH/GMPR family. GuaC type 1 subfamily.
