Cluster characterization in iron-sulfur proteins by magnetic circular dichroism.
We report magnetic circular dichroism (MCD) spectra of 4-Fe iron-sulfur clusters in the iron-sulfur proteins Chromatium high-potential iron protein (HIPIP), Bacillus stearothermophilus ferredoxin and Clostridium pasteurianum ferredoxin. The MCD is found to vary significantly with cluster oxidation state but is relatively insensitive to the nature of the protein. The spectra obtained are compar...

متن کاملMagnetic circular dichroism of porphyrin lanthanide M3+ complexes.
Lanthanide complexes exhibit interesting spectroscopic properties yielding many applications as imaging probes, natural chirality amplifiers, and therapeutic agents. However, many properties are not fully understood yet. Therefore, we applied magnetic circular dichroism (MCD) spectroscopy, which provides enhanced information about the underlying electronic structure to a series of lanthanide co...
متن کاملCircular Dichroism of Light-harvesting Complexes from Purple Photosynthetic Bacteria*
The CD spectra of a range of antenna complexes from several different species of purple photosynthetic bacteria were recorded in the wavelength range of 190 to 930 nm. Analysis of the far UV CD (190 to 250 nm) showed that in each case except for the B800-850 from Chr. vinosum the secondary structure of the light-harvesting complexes contains a large amount of a-helix ( 2 5 0 % ) and very little...
متن کاملOrganic Chemical Applications of Magnetic Circular Dichroism*
Recent applications of magnetic circular dichroism spectroscopy (the Faraday effect) in organic chemistry are reviewed. Magnetic optical activity is a universal property of all matter and consequently can be applied to optically active as well as optically inactive molecules. It is emphasized, however, that natural and magnetic optical activity have separate physical origins and the information...
