A Study on the Interaction Between Alkali Metal Ions and Groups of Polypeptides in the Gramicidin A Channell 在Gramicidin膜通道中碱金属离子与多肽基团之间的相互作用
This paper reports a computer simulation approach of molecular dynamics to study the correlations of ions K+, Na+ and Li+ to water molecules in a right-handed Gramicidin A model channel. 基于右手螺旋短杆菌肽A离子通道模型,利用分子动力学计算机模拟方法研究了通道内离子K+,Na+,Li+与水分子的相关性。
The gramicidin A-DMPC ( GA-DMPC) channel model was built with the new efficient approach for constructing the initial configuration. 用最近提出的构建膜体系初始构象的有效方法,构建了在DMPC脂膜环境下短杆菌肽A通道模型(GA-DMPC)。
