Cytosolic ITPA dimer catalyzes the reaction of XTP and water to form XMP and PPi (pyrophosphate). Mg++ is required for enzymatic activity. The hydrolysis of XTP is thought to prevent its incorporation into mRNA, which would lead to aberrant protein synthesis (Lin et al. 2001; Abolhassani et al. 2010).
Cytosolic ITPA dimer catalyzes the reaction of dITP and water to form dIMP and PPi (pyrophosphate). Mg++ is required for enzymatic activity. The hydrolysis of dITP is thought to prevent its incorporation into DNA, which would be mutagenic (Lin et al. 2001; Abolhassani et al. 2010).
