摘要: 运用分子动力学模拟与路径通道分析法研究细胞色素c(Cyt c)在银纳米团簇表面上的主要吸附驱动力、构象变化和电子转移的耦合矩阵元。结果表明,银纳米团簇表面电荷对电子转移至关重要。不带电的银纳米团簇有利于细胞色素c的吸附,且容易发生电子转移反应。

关键词: 细胞色素c, 银纳米团簇, 耦合矩阵元

Abstract: Molecular dynamics simulation and path channel analysis were performed to study the main adsorption driving force, conformational change, and electron transfer coupling matrix element of cytochrome c (Cyt c) on the surface of silver nanoclusters. The results show that the surface charge of silver nanoclusters is crucial for electron transfer. The uncharged silver nanoclusters facilitate the adsorption of Cyt c and are prone to electron transfer reactions.

Key words: cytochrome c, silver nanoclusters, coupling matrix element
