IUBMB Enzyme Nomenclature


Accepted name: inosine diphosphate phosphatase

Reaction: (1) IDP + H2O = IMP + phosphate
(2) dIDP + H2O = dIMP + phosphate

Other name(s): (deoxy)inosine diphosphatase; NUDT16

Systematic name: inosine diphosphate phosphatase

Comments: The human enzyme also hydrolyses GDP and dGDP, and to a lesser extent ITP, dITP and XTP.
