涉及局部塌陷和螺旋形成的早期事件，表现为从头肽的二硫键重组，在 1 ps 到 10 mu s 的时间范围内，同样适合拉伸指数 (alpha = 0.086 +/- 0.003) 和渐近幂律衰减 (beta = 0.331 +/- 0.004)。对于不均匀的复合动力学，每种衰变模式都会导致不同的弛豫时间分布。 (C) 1998 Elsevier Science B.V. 保留所有权利。
Early events involving local collapse and helix formation manifested by the disulphide recombination of a de-novo peptide, over the time scale from 1 ps to 10 mu s, are shown to fit equally well to a stretched exponential (alpha = 0.086 +/- 0.003) and by an asymptotic power-law decay (beta = 0.331 +/- 0.004). For inhomogeneous recombination kinetics each decay pattern leads to a different distribution of relaxation times. (C) 1998 Elsevier Science B.V. All rights reserved.
