Fe2+
-
the benzene dioxygenase comprises three components: 1. flavoprotein, NADH:ferredoxin oxidoreductase, 2. an intermediate electron-transfer protein, or ferredoxin with a [2Fe-2S] cluster and 3. a terminal dioxygenase, containing two [2Fe-2S]iron-sulfur clusters which require two additional Fe2+ atoms/molecules for oxygenase activity
Fe2+
-
the terminal dioxygenase component contains two Fe2+ ions per molecule in addition to two [2Fe-2S] iron-sulfur clusters
Fe2+
-
the alpha subunit of the enzyme contains a catalytic [2Fe-2S] cluster involved in electron transfer, the catalytic nonheme iron center is also responsible for substrate specificity, overview
-
the terminal dioxygenase component contains two Fe2+ ions per molecule in addition to two [2Fe-2S] iron-sulfur clusters. The ferredoxin component contains one [2Fe-2S] cluster
Iron
-
Rieske-type [2Fe-2S] centres are coordinated by two histidines and two cysteines
Iron
-
the sequence of the ferredoxin component of the benzene dioxygenase contains five Cys residues, four of which are required to coordinate the iron-sulfur cluster
Iron
-
the intermediate electron-carrying protein possesses on [2Fe-2S] cluster, the terminal dioxygenase possesses 2 [2Fe-2S] clusters
Iron
-
the terminal dioxygenase protein [2Fe-2S] centres, in the oxidized form the two iron atoms within the centre are high-spin ferric
