Magnetic Field Effects and Radical Pair Mechanisms in Enzymes:A Reappraisal of the Horseradish Peroxidase System

摘要

Presented here is a detailed reinvestigation of a reported magnetic field effect(MFE)in the haem-dependent enzyme horseradish peroxidase(HRP),using a stopped-flow device adapted to make high-precision single-wavelength measurements in the presence of a static magnetic field.We find substantial reappraisal of reported MFEs for this enzyme system is required.
