The activities of TdR kinase2 (ATP: thymidine 5'-phosphotransferase, EC 2.7.1.21), AdR kinase (ATP: deoxyadenosine 5'-phosphotransferase, EC 2.7.1.76), GdR kinase (ATP: deoxyguanosine 5'-phosphotransferase, without EC number), ATP (Mg2+)-ase (ATP phosphohydrolase, EC 3.6.1.3), nucleoside diphosphatase (nucleoside diphosphate phosphohydrolase, EC 3.6.1.6), nucleoside phosphotransferase (AMP: deoxynucleoside phosphotransferase, EC 2.7.1.77) and ribonucleotide 5'-diphosphate reductase (EC 1.17.4.1) were assayed in mitochondria of normal and regenerating rat liver. The activities of deoxynucleoside kinases are regulated: (a) by feedback inhibition of TdR kinase with dTTP and dCTP, and GdR kinase with dGTP; (b) GdR and AdR kinases by AdR and GdR inhibition, respectively; (c) by stimulation of GdR kinase with dTDP, dTTP and dATP. The stimulatory effects are correlated with changes of ATP (Mg2+)-ase and NDP-ase activities in regenerating liver mitochondria.
