    Abstract

    Electron-transfer processes play a vital role in many biological phenomena, from energy storage to photosynthesis. The labelled electron method using positive muons allows such transfer processes in macromolecules, such as proteins, to be probed on a microscopic level. Here we present the results of an experiment using the labelled electron method with mSR to investigate electron-transfer processes in apoferritin. The data is well described using the Risch–Kehr model and the results suggest one dimensional, or intra-chain diffusion occurs in this system. Intra-chain diffusion rates of 1012 rad/s have been determined.
