1.3.5.1 | FAD | stoichiometric ratio between covalently bound FAD and the iron-sulfur cluster is 1:1. Protoheme IX is present in about 2:1 stoichiometry to covalently bound FAD | Chloroflexus aurantiacus | |
1.3.5.1 | heme | enzyme contains about 11 iron atoms per complex, which is expected if the enzyme contains one [2Fe-2S] cluster, one [3Fe-4S] cluster, one [4Fe-4S] cluster and two type b hemes. Protoheme IX is present in about 2:1 stoichiometry to covalently bound FAD | Chloroflexus aurantiacus | |
1.3.5.1 | iron-sulfur centre | enzyme contains about 11 iron atoms per complex, which is expected if the enzyme contains one [2Fe-2S] cluster, one [3Fe-4S] cluster, one [4Fe-4S] cluster and two type b hemes. The purified mQFR complex has two iron-sulfur centers of the ferredoxin type that are paramagnetic in the reduced state, 2Fe-2S and 4Fe-4S, and one iron-sulfur center of the high potential type that is paramagnetic in the oxidized state, 3Fe-4S. Centers 2Fe-2S and 4Fe-4S exhibit a large difference in their redox midpoint potential, center 2Fe-2S is reducible with succinate, whereas the latter one can only be reduced by very low potential reductant such as dithionite | Chloroflexus aurantiacus | |
