in the native state, two clusters of the enzyme are in the [4Fe-4S]2+ oxidized state
4Fe-4S containing protein. Oxidation state of +2 for the 4Fe-4S cluster, with no disulfide bond in the holoenzyme
PpAPR-B does not contain the FeS cluster, which is believed to determine the substrate specificity of other APR enzymes from seed plants. The lack of the FeS cluster in PpAPR-B catalysis is connected with a lower turnover rate but higher stability of the protein
