Yuhong Wang, Wei Li, Hongmao Sun, Kennie Cruz-Gutierrez

摘要:

在给定的二维接触图下,蛋白质三维结构的重建精度可达2 A或更高,是解决蛋白质折叠问题的一种可行的计算方法。传统方法的预测准确性通常太差而无法使用,但最近的深度学习模型显着提高了准确性。在这项研究中,我们提出了一个神经网络模型,包括一个双向循环神经网络和人工神经网络。在Protein Data Bank中所有可用蛋白质3D结构的非冗余数据库中,该深度学习模型的准确率达到0.80,远高于以前的模型。这项研究代表了蛋白质2D接触图预测的重大突破,并可能是蛋白质折叠问题的重要一步。

英文摘要:

Given native 2D contact map, protein 3D structure could be reconstructed with accuracy of 2A or better, and such reconstruction is a feasible computational approach for protein folding problem. The prediction accuracy from traditional methods is generally too poor to useful, but the recent deep learning model has significantly improved the accuracy. In this study, we proposed a neural network model comprising a bi-directional recurrent neural network and artificial neural network. Over the non-redundant database of all available protein 3D structures in Protein Data Bank, this deep learning model achieved an accuracy of 0.80, much higher than those of previous models. This study represents a major breakthrough in protein 2D contact map prediction and likely a major step forward for the protein folding problem.
