[The effect of ionizing radiation on Ca ATPase of erythrocyte membranes].
Erythrocyte ghosts were irradiated with doses of 4 x 10(-3)-10(3) Gy. The activity of Ca(2+)-ATPase, the kinetic characteristics of enzyme reaction, the Hill's coefficient, the association constant and a number of La3+ linking centers were determined. The structural--functional peculiarities of Ca(2+)-ATPase changes under exposure to 4 x 10(-3) and 40 Gy of ionizing radiation have been established.
