[(3)H]N(6)-(Ethyl 2-diazomalonyl)-adenosine 3':5'-cyclic monophosphate is incorporated into intact ghosts from human erythrocytes on photolysis at 253.7 nm. Incorporation is blocked in the presence of adenosine 3':5'-cyclic monophosphate (cyclic AMP) and does not occur in the absence of irradiation. Sodium dodecyl sulfate disc gel electrophoresis of solubilized ghosts shows that one protein is labeled. The position of this protein on the gel corresponds exactly to that previously found. [J.

在253.7nm光解时,[(3)H]N(6)-(乙基2-重氮丙二酰基)-腺苷3':5'-环一磷酸被掺入人红细胞的完整细胞膜空壳中。在腺苷3':5'-环一磷酸(环磷酸腺苷)存在的情况下,掺入被阻断,并且在没有照射的情况下不会发生。对溶解的细胞膜空壳进行十二烷基硫酸钠圆盘凝胶电泳显示有一种蛋白质被标记。该蛋白质在凝胶上的位置与先前发现的完全一致。[《生物化学杂志》247, 8145(1972)]中内源性环磷酸腺苷依赖性蛋白激酶的内源性蛋白质底物的位置。
