[Enzymes of NAD+ catabolism in differentiating rabbit erythroid cells].
A study was made of the hydrolysis of NAD+ in the process of rabbit erythroid cell differentiation. Activities of NAD-hydrolase and NAD-pyrophosphatase, examined during maturation of erythroid cells, demonstrated a more significant decrease in the course of erythroblast-reticulocyte transformation, than at the next step of erythropoesis (reticulocyte-erythrocyte transformation). Both enzymes are strongly associated with the stroma. Under discussion is a question of the possible role of NAD+ catabolism.
