The competition between chemistry and biology in assembling iron–sulfur derivatives. Molecular structures and electrochemistry. Part I. {Fe(SγCys)4} proteins
چکیده انگلیسی

In the present review, we focus on the relationships between molecular geometry and electron transfer ability of the different classes of proteins bearing the {Fe(SγCys)4} core as active site. We will highlight the role played by the amino acid composition in determining the redox activity of rubredoxins, flavorubredoxins, rubrerythrins, nigerythrins, desulfoferrodoxins and desulforedoxins, including, when available, their mutants. We will conclude with the electrochemical and structural aspects of synthetic FeS4 derivatives able to mimic the above cited proteins (usually the rubredoxins).

► We illustrate structure and electrochemistry of proteins containing {Fe(SγCys)4}core(s).
► We present the structural changes consequent to Fe(III)/Fe(II) passage in {Fe(SγCys)4} proteins.
► We examine structure/electrochemistry of synthetic iron-tetrathiolate mimicking {Fe(SγCys)4} proteins.
