| Abstract: | The mechanism of the reduction of pentacyanoferrate(III) complexes by oxymyoglobin has been studied by conventional and high-pressure
kinetic methods, and also by structural modelling. The results of this and an earlier study show that an outer-sphere mechanism
is operating for electron transfer between oxymyoglobin and FeIII(CN)5L
n
–, independent of the lability of the ligand L. The electron transfer process is preceded by precursor formation at a specific
site on the protein close to the protein heme pocket.
