IntEnz Enzyme Nomenclature
EC 3.1.3.99

Names

Accepted name:
IMP-specific 5'-nucleotidase
Other name:
ISN1 (gene name)
Systematic name:
inosine 5'-phosphate phosphohydrolase

Reaction

Cofactor

Comments:

The enzyme, isolated from the yeast Saccharomyces cerevisiae, is highly specific for inosine 5'-phosphate, and has no detectable activity with other purine and pyrimidine nucleotides. Requires divalent metals, such as Mg2+, Co2+ or Mn2+.
