Comments [?]

Function Involved in the purine-salvage pathway. Catalyzes the NADPH-dependent conversion of GMP to IMP.
Catalytic activity RHEA:17185: IMP + NADP(+) + NH4(+) = GMP + 2 H(+) + NADPH
EC 1.7.1.7
PhysiologicalDirection=right-to-left (RHEA:17187)
Cofactor a monovalent cation
Pathway Purine metabolism; IMP biosynthesis via salvage pathway.
Similarity Belongs to the IMPDH/GMPR family. GuaB1 subfamily.
