Abstract

An empirical equation, describing the relationship between the porphyrin methyl hyperfine shifts and the position of the axial ligand(s), has been applied to an artificial heme-protein in order to obtain insight into the active site properties of heme-protein models.

This article is part of the themed collection: Biological oxidation reactions: mechanisms and design of new catalysts
