摘要: The fumarate reductase complex and soluble enzyme from Escherichia coli have been investigated by low temperature magnetic circular dichroism electron paramagnetic resonance spectroscopies. results confirm the presence of one [2Fe-2S] cluster show that high potential iron-sulfur center is a 3Fe type found in bacterial ferredoxins. Since present catalytically competent does not appear to be involved any conversion under reducing conditions, we conclude it an intrinsic component functional enzyme. significance discussed relation published amino acid sequence composition reductases.
