abstract = {Heme enzymes activate oxygen through formation of transient
iron-oxo (ferryl) intermediates of the heme iron. A
long-standing question has been the nature of the
iron-oxygen bond and, in particular, the protonation state.
We present neutron structures of the ferric derivative of
cytochrome c peroxidase and its ferryl intermediate; these
allow direct visualization of protonation states. We
demonstrate that the ferryl heme is an Fe(IV)=O species and
is not protonated. Comparison of the structures shows that
the distal histidine becomes protonated on formation of the
ferryl intermediate, which has implications for the
understanding of O–O bond cleavage in heme enzymes. The
structures highlight the advantages of neutron
cryo-crystallography in probing reaction mechanisms and
visualizing protonation states in enzyme intermediates.},
