采用Fokker-Planck方程研究了甘油分子在周期性外力作用下通过甘油通道(glycerol protein ficilitator,GlpF)定向输运的问题.根据平均力势(potential of mean force,PMF)的分布把GlpF分成14个区域,分别讨论了不同区域对甘油分子定向输运的影响.研究发现,GlpF的中间区域对甘油分子的输运起到关键作用.
By using Fokker-Planck equation, it was investigated the unidirectional through GlpF driven by periodic external force. According to the profile of the PMF, 14 regions. Effects of these regions on the glycerol transportation were studied. The transportation of glycerol the GlpF was divided into theoretical results indica- ted that the middle region of the GlpF played a key role in glycerol transportation .
