A good correlation was observed between the reciprocal of the half-life of ornithine decarboxylase (ODC) activity in the presence of cycloheximide and the relative amount of ODC-antizyme complex to total ODC (free ODC plus complexed ODC) activity in HTC cells examined at various times after cell dilution or change of medium. Pretreatment of cells with putrescine increased the relative amount of ODC-antizyme complex and decreased the half-life of ODC decay. These results suggested that antizyme plays a key role in ODC degradation.
在细胞稀释或更换培养基后的不同时间检测HTC细胞时,观察到在放线菌酮存在的情况下鸟氨酸脱羧酶(ODC)活性半衰期的倒数与ODC-抗酶复合物相对于总ODC(游离ODC加上复合ODC)活性的相对量之间存在良好的相关性。用腐胺预处理细胞可增加ODC-抗酶复合物的相对量,并缩短ODC降解的半衰期。这些结果表明抗酶在ODC降解中起关键作用。
