Desulfoferrodoxin; Catalyzes the one-electron reduction of superoxide anion radical to hydrogen peroxide at a nonheme ferrous iron center. Plays a fundamental role in case of oxidative stress via its superoxide detoxification activity (By similarity). oxidized rubredoxin + H(2)O(2). Name=Fe(3+); Xref=ChEBI:CHEBI:29034; Evidence=; Note=Binds 1 Fe(3+) ion per subunit. The iron ion 1 is coordinated via 4 cysteine residues; Name=Cu(2+); Xref=ChEBI:CHEBI:29036; Evidence=; Note=Binds 1 Fe(2+) ion per subunit. The iron ion 2 is coordinated via four histidines and one cysteine residue.; has a [...]

Digeranylgeranylglyceryl phosphate synthase; Prenyltransferase that catalyzes the transfer of the geranylgeranyl moiety of geranylgeranyl diphosphate (GGPP) to the C2 hydroxyl of (S)-3-O-geranylgeranylglyceryl phosphate (GGGP). This reaction is the second ether-bond-formation step in the biosynthesis of archaeal membrane lipids.

Nitrogenase iron protein 2; The key enzymatic reactions in nitrogen fixation are catalyzed by the nitrogenase complex, which has 2 components: the iron protein and the molybdenum-iron protein; Belongs to the NifH/BchL/ChlL family.
