Abstract

The water-proton fast exchange between the vicinity of the ferric haemiron and bulk solvent in horseradish peroxidase solutions at neutral pH has been directly verified by measuring the proton magnetic relaxation times of the aliphatic protons from ethanediol in an otherwise deuterated solution. The implications of this finding are discussed with regard to the stereochemistry of the haem-surrounding.
