In mitochondria, two mono heme c-type cytochromes are essential electron shuttles of the respiratory chain. They are characterized by the covalent attachment of their heme C to a CXXCH motif in the apoproteins. This post-translational modification occurs in the intermembrane space compartment. Dedicated assembly pathways have evolved to achieve this chemical reaction that requires a strict reducing environment. In mitochondria, two unrelated machineries operate, the rather simple System III in… CONTINUE READING
