Abstract
DPN pyrophosphorylase activity has been demonstrated in chicken erythrocytes, but could not be found in rabbit reticulocytes nor in human or rabbit erythrocytes. In the erythrocyte of the chicken, the activity was confined to the particulate fraction, which consists mainly of cell nuclei. The implications of these findings with respect to the maturation of the erythrocyte and the metabolic interrelationship between the nucleus and the cytoplasm are discussed.
