General annotation (Comments)

Function

May have a critical role in the maintenance of a constant composition of intracellular purine/pyrimidine nucleotides in cooperation with other nucleotidases. Preferentially hydrolyzes inosine 5'-monophosphate (IMP) and other purine nucleotides By similarity.

Catalytic activity

A 5'-ribonucleotide + H2O = a ribonucleoside + phosphate.

Cofactor

Binds 1 magnesium ion per subunit By similarity.

Enzyme regulation

Allosterically activated by various compounds, including ATP By similarity.

Subcellular location

Cytoplasm By similarity.

Sequence similarities

Belongs to the 5'(3')-deoxyribonucleotidase family.
