Abstract
The separation of catalytic cAMP-independent and regulatory cAMP-binding subunits of pigeon breast muscle protein kinase was performed after the treatment of the holoenzyme by cAMP. The molecular weight of the homogeneous catalytic subunit is determined as 30,000. When catalytic and regulatory subunits were mixed, the decrease of phosphotransferase activity was observed.
摘要
通过环磷酸腺苷（cAMP）处理全酶后，对鸽胸肌蛋白激酶的催化性非cAMP依赖性亚基和调节性cAMP结合亚基进行了分离。均一催化亚基的分子量测定为30,000。当催化亚基和调节亚基混合时，观察到磷酸转移酶活性降低。
