title: [Aldolase binding by ghosts and plasma membranes of differentiating erythroid cells in pigeons].
abstract: During the differentiation of pigeon erythroid cells their aldolase activity considerably decreases, which is more obvious during the erythroblast reticulocyte development compared to the reticulocyte erythrocyte development. There are some common patterns in the character of aldolase binding by plasma membrane (PM) of the erythroid cells of different degrees of maturation: a high binding lability and the availability of a small portion of enzyme firmly bound to PM. During erythropoesis an increase of aldolase binding occurs. The provided data show a specific character of interaction of aldolase with erythroid membrane. The shown increase of aldolase binding may partly explain a decrease of its activity in the course of erythropoesis and is, perhaps, of adaptive character.
