EC 3.6.1.66 Details
EC number
3.6.1.66
Accepted name
XTP/dITP diphosphatase
Reaction
(1) XTP + H2O = XMP + diphosphate;;(2) dITP + H2O = dIMP + diphosphate;;(3) ITP + H2O = IMP + diphosphate
Other name(s)
hypoxanthine/xanthine dNTP pyrophosphatase, rdgB (gene name)
Systematic name
XTP/dITP diphosphohydrolase (diphosphate-forming)
Comment
The enzymes from the bacterium Escherichia coli and the archaea Methanococcus jannaschii and Archaeoglobus fulgidus are highly specific for XTP, dITP and ITP. The activity is dependent on divalent cations, Mg2+ is preferred.
