蛋白质非线性网络模型中的能量传递

Energy transfer in nonlinear network models of proteins

Francesco Piazza, Yves-Henri Sanejouand

摘要:

我们研究了非线性和拓扑无序如何影响蛋白质粗粒度网络模型中局部踢的能量弛豫。我们发现,非线性促进远程,相干转移大量的能量到特定的,功能性的网站,而压抑转移到通用的位置。值得注意的是,转移可以介导的自我定位的离散呼吸在遥远的位置从踢,作为有效的能量积累中心。

英文摘要:

We investigate how nonlinearity and topological disorder affect the energy relaxation of local kicks in coarse-grained network models of proteins. We find that nonlinearity promotes long-range, coherent transfer of substantial energy to specific, functional sites, while depressing transfer to generic locations. Remarkably, transfer can be mediated by the self-localization of discrete breathers at distant locations from the kick, acting as efficient energy-accumulating centers.
