Ligand substitution at the metal center is common in catalysis and signal transduction of metalloproteins. Understanding the effects of particular ligands, as well as the polypeptide surrounding, is critical for uncovering mechanisms of these biologi

Ligand-switch reactions at the heme iron are common in biological systems, but their mechanisms and the features of the polypeptide fold that support dual ligation are not well understood. In cytochrome c (cyt c), two low-stability loops (Ω-loop C a

At low oxygen concentrations, respiration of Pseudomonas aeruginosa (Pa) and other bacteria relies on activity of cytochrome cbb3 oxidases. A diheme cytochrome c4 (cyt c4) donates electrons to Pa cbb3 oxidases to enable oxygen reduction and proton pu

Met80, one of the heme iron ligands in cytochrome c (cyt c) is readily oxidized to Met sulfoxide (Met-SO) by several biologically-relevant oxidants. The modification has been suggested to impact both the electron-transfer (ET) and apoptotic functions

Mechanistic studies of proton-coupled electron-transfer (PCET) reactions in proteins are complicated by the challenge of following proton transfer (PT) in these large molecules. Herein we describe the use of isothermal titration calorimetry (ITC) to
