Cytochrome c (cyt c) is a small soluble heme protein characterized by a relatively flexible
structure, particularly in the ferric form, such that it is able to sample a broad conformational …

The reduction potential (E°′) is a critical parameter in determining the efficiency of most
biological and chemical reactions. Biology employs three classes of metalloproteins to cover …

In this overview we present recent combined electrochemical, spectroelectrochemical,
spectroscopic and computational studies from our group on the electron transfer reactions of …

We have employed a combination of protein film voltammetry, time-resolved vibrational
spectroelectrochemistry and molecular dynamics simulations to evaluate the electron …

The Marcus theory of electron transfer (ET) predicts that while the ET rate constants increase
with rising driving force until it equals a reaction's reorganization energy, at higher driving …

This work explores the concept that differential wave function overlap between excited states
can be engineered within a molecular chromophore. The aim is to control excited state wave …

PmoD, a recently discovered protein from methane-oxidizing bacteria, forms a homodimer
with a dicopper CuA center at the dimer interface. Although the optical and electron …

Here we report the effect of molecular crowding on long-range protein electron transfer (ET)
and disentangle the specific responses of the redox site and the protein milieu. To this end …

Nonexponential distance dependence of the apparent electron-transfer (ET) rate has been
reported for a variety of redox proteins immobilized on biocompatible electrodes, thus …

Within Cu-containing electron transfer active sites, the role of the axial ligand in type 1 sites
is well defined, yet its role in the binuclear mixed-valent CuA sites is less clear. Recently, the …
