Abstract

Myosin from molluscan adductor muscle is regulated directly by Ca2+ binding. In the absence of Ca2+ the ATPase activity is greatly inhibited. We review the application of transient kinetic methods to this system and show how they can be simple to perform and less ambiguous than steady-state methods.

动态分析调节肌球蛋白atp酶活性使用单一和有限的周转分析。
软体动物内收肌肌球蛋白直接受Ca2+结合调节。在缺乏Ca2+的情况下,atp酶活性被极大地抑制。我们回顾了瞬态动力学方法在该系统中的应用,并展示了它们如何比稳态方法更容易执行和更少模糊。
