Cytosolic phosphoribosyl pyrophosphate synthetase 1 catalyzes the reaction of D-ribose 5-phosphate and dATP to form 5-phospho-alpha-D-ribose 1-diphosphate and 2'-deoxyadenosine 5'-monophosphate. While phosphoribosyl pyrophosphate synthetase 1 works well with either ATP or dATP as a substrate in vitro, the extent of the dATP reaction in vivo is unclear, as cellular dATP concentrations are normally very low (Fox and Kelley 1971).
