Fe
the purified catalytic subunit HrdD contains 7.0 mol non-heme iron per mol monomer
Fe2+
[2Fe-2S] cluster core with complete cysteinyl ligation in center C, sensitive to dithionite
Iron
1 mol H2: heterodisulfide oxidoreductase complex with MW 250000 Da contains approximately 26 mol non-heme iron
Iron
active-site [4Fe-4S] cluster that is directly involved in mediating heterodisulfide reduction
Iron
coenzyme M binds to a [4Fe-4S] cluster in the active site
Iron
contains an active-site [4Fe-4S] cluster that is directly involved in mediating heterodisulfide reduction
Iron
contains two [Fe4S4] clusters. Only the low spin heme and the high potential FeS cluster are involved in reduction of N-(7-[(2-sulfoethyl)dithio]heptanoyl)-3-O-phospho-L-threonine. A 4 Fe cluster is the initial electron acceptor
Iron
the C-terminal CCG domain of the subunit B of heterodisulfide binds to the [4Fe-4S]3+ cluster
Iron
the enzyme contains 280 nmol of non-heme iron per mg of protein
Iron
the enzyme contains two distinct [Fe4S4]2+/1+ clusters in the large subunit
