CC -!- FUNCTION: Involved in the purine-salvage pathway. Catalyzes the NADPH-
CC dependent conversion of GMP to IMP. {ECO:0000256|HAMAP-Rule:MF_02250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=IMP + NADP(+) + NH4(+) = GMP + 2 H(+) + NADPH;
CC Xref=Rhea:RHEA:17185, ChEBI:CHEBI:15378, ChEBI:CHEBI:28938,
CC ChEBI:CHEBI:57783, ChEBI:CHEBI:58053, ChEBI:CHEBI:58115,
CC ChEBI:CHEBI:58349; EC=1.7.1.7; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_02250};
CC -!- COFACTOR:
CC Name=a monovalent cation; Xref=ChEBI:CHEBI:60242;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_02250};
CC -!- PATHWAY: Purine metabolism; IMP biosynthesis via salvage pathway.
CC {ECO:0000256|HAMAP-Rule:MF_02250}.
CC -!- SIMILARITY: Belongs to the IMPDH/GMPR family. GuaB1 subfamily.
CC {ECO:0000256|HAMAP-Rule:MF_02250}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
