The nuclei of pigeon erythrocytes are capable of synthesizing NAD from nicotinamid-mononucleotides and ATP. Some data on the kinetics of NAD-pyrophosphorylase have been obtained: the optimal concentration of nuclei and the effect of various incubation time. The pretreatment of nuclei by Triton X-100, or by ultrasonics enhances NAD synthesis. The results suggest that cyclic 3',5'-AMP (Fluka) may have no effect on NAD synthesis. The control of the cell metabolism by NAD formation is considered.
