The electron paramagnetic resonance of metalloproteins.
E.p.r. is a spectroscopic technique that probes the environment of a paramagnetic centre by defining tlie size and shape of the magnetic moment produced by the unpaired electron. and by characterizing any magnetic fields which might be produced by the parent molecule in the vicinity of the paramagnetic centre. In the context of our interests, these unpaired electrons are found either in selecte...
متن کاملPerspectives in paramagnetic NMR of metalloproteins.
NMR experiments and tools for the characterization of the structure and dynamics of paramagnetic proteins are presented here. The focus is on the importance of (13)C direct-detection NMR for the assignment of paramagnetic systems in solution, on the information contained in paramagnetic effects observed both in solution and in the solid state, and on novel paramagnetism-based tools for the inve...
متن کاملMultifrequency pulsed electron paramagnetic resonance on metalloproteins.
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...
متن کاملPSEUDYANA for NMR structure calculation of paramagnetic metalloproteins using torsion angle molecular dynamics.
The program DYANA, for calculation of solution structures of biomolecules with an algorithm based on simulated annealing by torsion angle dynamics, has been supplemented with a new routine, PSEUDYANA, that enables efficient use of pseudocontact shifts as additional constraints in structure calculations of paramagnetic metalloproteins. PSEUDYANA can determine the location of the metal ion inside...
متن کاملStructure-Function Relationship of Metalloproteins
Metalloproteins are a class of biologically important macromolecules, which have various functions such as oxygen transport, electron transfer, oxidation, and oxygenation. These diverse functions of metalloproteins have been thought to depend on the ligands from amino acid, coordination structures, and protein structures in immediate vicinity of metal ions. In this project, we are studying the ...
