1.7.5.1 | Fe | the four iron-sulfur centers of nitrate reductase A belong to two classes with markedly different redox potentials. The high-potential group comprises a [3Fe-4S] and a [4Fe-4S] cluster whose midpoint potentials are +60 mV and +80 mV, respectively. Although these centers are magnetically isolated, they are coupled by a significant anticooperative redox interaction of about 50 mV. The [4Fe-4S]1+ center occurs in two different conformations as shown by its composite EPR spectrum. The low-potential group contains two [4Fe-4S] clusters with more typical redox potentials (-200 mV and -400 mV). In the fully reduced state, the three [4Fe-4S]1+ centers are magnetically coupled. The iron-sulfur centers nitrate reductase Z and nitrate reductase A, exhibit essentially the same characteristics, except that the midpoint potentials of the high-potential centers of nitrate reductase Z appear negatively shifted by about 100 mV. A correspondence between the high-potential iron-sulfur clusters of the two enzymes can be proposed | Escherichia coli |
