the activity of various triphosphate nucleosides as a phosphate donor for cytoplasmic deoxythymidine kinase is as follows : atp = datp greater than ara-atp greater than gtp greater than ctp greater than dgtp = dctp greater than dutp , whereas for mitochondrial deoxythymidine kinase , the order of activity is atp greater than ctp greater than utp = datp greater than ara-atp greater than dgtp = dctp greater than dutp .
