Metalloproteins often contain metal centers that are paramagnetic in some functional state of the protein; hence electron paramagnetic resonance (EPR) spectroscopy can be a powerful tool for studying protein structure and function. Dipolar spectroscopy allows the determination of the dipole-dipole interactions between metal centers in protein complexes, revealing the structural arrangement of d...
ABSTRACT A series of dioxygen complexes of copper, iron, and manganese have been synthesized using bulky tripodal nitrogen ligands, hydrotris(3,5-dialkyl1-pyrazolyl)borate, as models for the active sites in the metalloproteins. A binuclear copper peroxo complex having p-q2:$ coordination mode serves as an accurate model of the active site of oxy-hemocyanin. The reactivities of the complex and r...
This broad overview covers the use of gas and liquid chromatography as well as capillary electrophoresis for the determination of metal ions and metalcontaining species, such as organometallic compounds or metalloproteins. We pay particular attention to the latest developments and consider the features of the various detection techniques and applications of the different methods. a 2005 Elsevie...
Truncated acetyl-coenzyme A synthase (ACS) was successfully converted into functional nickel superoxide dismutase (Ni-SOD) by molecular design and the designed metalloproteins possess new spectroscopic, structural, and electrochemical characteristics required for catalyzing O(2)(˙-) disproportionation, and exhibit impressive Ni-SOD activity.
