PyGBe是一个Python代码,用于在连续介质模型中应用边界元法进行分子静电计算。它计算与任何数量的介电区域建模的蛋白质的溶剂化能,这与蛋白质结合亲和力,蛋白质-表面相互作用,酸解离常数等应用的计算有关。数学公式遵循Yoon和Lenhoff(1990),用于以积分形式求解隐式溶剂模型的Poisson-Boltzmann方程。
PyGBe—pronounced pigbē—is a Python code to apply the boundary element method for molecular-electrostatics calculations in a continuum model. It computes solvation energies for proteins modeled with any number of dielectric regions, which is relevant in calculations of protein binding affinity, protein-surface interaction, acid-dissociation contants, among other applications. The mathematical formulation follows Yoon and Lenhoff (1990) for solving the Poisson-Boltzmann equation of the implicit-solvent model in integral form.
