- Abstract:
-
In clostridial-type ferredoxins, each of the two [4Fe-4S]2+/+ clusters receives three of its four ligands from a CysXXCysXXCys motif. Azotobacter vinelandii ferredoxin I (AvFdI) is a seven-iron ferredoxin that contains one [4Fe-4S]2+/+ cluster and one [3Fe-4S]+/0 cluster. During the evolution of the 7Fe azotobacter-type ferredoxins from the 8Fe clostridial-type ferredoxins, one of the two motifs present changed to a CysXXCysXXXXCys motif, resulting in the inability to form a 4Fe cluster and t...
