摘要 该文利用蛋白质的一级结构信息,将支持向量机应用于人的蛋白质相互作用预测中,采用三肽频数方法刻画蛋白质序列.计算结果表明,该方法能准确预测人的蛋白质相互作用.比较了半胱氨酸在不同分类下对预测结果的影响,对人的胚胎肝脏蛋白质相互作用网络进行预测,为实验提供了重要的信息。 Support vector machine is used to predict protein-protein interaction of Homo sapiens through the protein s primary sequence.A conjoint triad feature is used to describe amino acids.Experimental results show that the method can predict PPIs with high accuracy.The predicted results of two classifications of Cys are compared. The PPI network of human fetal liver is predicted,which supplies important information for experiments.
