... exists on the role of this protein in the biogenesis of heme-containing proteins in plants. To gain insight into this process, we decided to study the role of frataxin using the enzyme catalase ... group synthe- sis and frataxin deficiency might have an impact in Fe–S and heme-containing protein biogenesis. On the other hand, it has been reported that frataxin interacts with FC...
