EC 3.6.1.66 Details

show Brenda entry

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.
