EISA-Score:用于蛋白质-配体结合亲和力预测的元素相互作用表面积评分

EISA-Score: Element Interactive Surface Area Score for Protein-Ligand Binding Affinity Prediction

Md Masud Rana, Duc Duy Nguyen

摘要:

分子表面表征被认为是研究蛋白质结构和功能的重要工具,包括蛋白质-配体结合亲和力建模。然而,传统的基于表面积的方法无法提供有竞争力的性能上的能量评分任务。主要原因是缺乏关键的物理和化学相互作用编码的分子表面代。我们提出了新的分子表面表示嵌入在不同尺度的元素交互流形具有显着的降维和准确的物理和生物特性编码器。这些低维基于表面的描述符可以与任何先进的机器学习算法配对,以探索产生基于元素交互表面积的评分函数(EISA-score)的基本结构-活性关系。新开发的EISA-score在标准PDBbind基准测试中的表现优于许多最先进的模型,包括各种成熟的表面相关表示。

英文摘要:

Molecular surface representations have been advertised as a great tool to study protein structure and functions, including protein-ligand binding affinity modeling. However, the conventional surface-area-based methods fail to deliver a competitive performance on the energy scoring tasks. The main reason is the lack of crucial physical and chemical interactions encoded in the molecular surface generations. We present novel molecular surface representations embedded in different scales of the element interactive manifolds featuring the dramatically dimensional reduction and accurately physical and biological properties encoders. Those low-dimensional surface-based descriptors are ready to be paired with any advanced machine learning algorithms to explore the essential structure-activity relationships that give rise to the element interactive surface area-based scoring functions (EISA-score). The newly developed EISA-score has outperformed many state-of-the-art models, including various well-established surface-related representations, in standard PDBbind benchmarks.
