Reaction: (1) N7-methyl-GMP + H2O = N7-methyl-guanosine + phosphate
(2) CMP + H2O = cytidine + phosphate
Other name(s): cytosolic nucleotidase III-like; cNIII-like; N7-methylguanylate 5'-phosphatase
Systematic name: N7-methyl-GMP phosphohydrolase
Comments: The enzyme also has low activity with N7-methyl-GDP, producing N7-methyl-GMP. Does not accept AMP or GMP, and has low activity with UMP.
