ResumoThe metabolic changes induced by the deoxycoformycin inhibition of adenosine deaminase were studied in human erythrocytes incubated with nucleosides. 1 Adenosine nucleotide levels and glycolytic rate were increased by adenosine. 2 With deoxyadenosine, the cellular ATP level was reduced when dATP increased and the glycolytic rate was similarly enhanced. 3 The hypoxanthine production was equivalent in both cases. Our data demonstrate that human red cells are able to catabolize adenine deoxynucleotides into hypoxanthine, and the control of energy metabolism is not impaired by adenosine deaminase inhibition when PO4 and NAD+ are not limiting.
