Abstract

Administration of adrenaline to an isolated rat hindlimb preparation rapidly decreased muscle phosphorylase phosphatase (EC 3.1.3.17) activity and increased heat-stable and trypsin-labile phosphatase inhibitor activity. This was associated with increased tissue cyclic AMP concentrations, phosphorylase (EC 2.4.1.1) activation and glycogen synthase (EC 2.4.1.11) inactivation.

摘要

给离体大鼠后肢标本注射肾上腺素后,肌肉磷酸化酶磷酸酶(EC 3.1.3.17)活性迅速降低,热稳定且对胰蛋白酶敏感的磷酸酶抑制剂活性增加。这与组织环磷酸腺苷浓度升高、磷酸化酶(EC 2.4.1.1)激活及糖原合酶(EC 2.4.1.11)失活有关。
