Abstract
Polymerized actin hydrolyzes bound ATP in a reaction that depends on the concentration of polymerized ATP-actin, not on the rate of incorporation of ATP-actin into the polymer. The apparent first order rate constant is about 0.07 s-1 at 21 degrees C in 50 mM KCl with 1 mM MgCl2 or CaCl2.
摘要
聚合肌动蛋白在一个依赖于聚合ATP-肌动蛋白浓度而非ATP-肌动蛋白掺入聚合物速率的反应中水解结合的ATP。在含有1 mM MgCl2或CaCl2的50 mM KCl中，21摄氏度时表观一级速率常数约为0.07 s-1。
