我们已经开发了一个定量的计算机模型,它模拟了海胆卵受精后蛋白质合成的增加。该模型预测的放射性标记的氨基酸掺入蛋白质的实验情况下,其中的氨基酸池标记前受精的动力学。该计算机模型被用来检查的主要参数,如蛋白质合成的起始时间的值的变化的影响,在mRNA被揭露的速率,核糖体的运输时间,和标记的氨基酸池的消耗率的氨基酸掺入的动力学。当使用这些参数的实验确定值时,模型预测的动力学非常接近在新受精卵中实际观察到的动力学。我们认为,mRNA的翻译速度和受精后延长率的变化控制蛋白质合成的增加,这两个过程都是在初始受精事件后0-2分钟内启动的。
We have developed a quantitative computer model which simulates the rise in protein synthesis resulting from the fertilization of the sea urchin egg. The model predicts the kinetics of incorporation of radioactively labeled amino acids into proteins for the experimental situation in which the amino acid pool is labeled prior to fertilization. The computer model is used to examine the impact of changes in the values of major parameters such as the time of initiation of protein synthesis, the rate at which mRNA is unmasked, the ribosome transit time, and the rate of depletion of the labeled amino acid pool on the kinetics of amino acid incorporation. When experimentally determined values for these parameters are used the model predicts kinetics which closely approximate the kinetics actually observed in newly fertilized eggs. We suggest that the rate at which mRNA is made available for translation and a change in the elongation rate following fertilization control the rise in protein synthesis, and that both of these processes are initiated within 0–2 min following the initial fertilization event.
