生物电子转移中的关键问题之一是确定空间中间氨基酸残基在控制或指导氧化还原位点之间的电子隧穿相互作用中的作用。发展了一种量子路径积分蒙特卡罗方法,用于分析高度结构化环境中的电子隧穿路径。将此路径积分方法应用于在“飞行线”中含有色氨酸的经修饰的肌红蛋白中的分子内电子转移。“一个主要的结果是确定了被隧穿电子扫过的相关圆柱形区域。
One of the crucial issues in biological electron transfer is the determination of the role of spatially intermediate amino acid residues in controlling or directing the electronic tunneling interaction between redox sites. A quantum path integral Monte Carlo method is developed for the analysis of electronic tunneling pathways in a highly structured environment. This path integral method is applied to intramolecular electron transfer in a ruthenium-modified myoglobin that contains a tryptophan in the "line-of-flight." A principal result is the identification of the relevant cylindrical zone swept out by the tunneling electron.
