Metalloproteins represent a substantial fraction of the proteome where they have an outsized contribution to enzymology. This stems from the reactivity of transition metals found in the active sites of numerous classes of enzymes that undergo redox and/or spin-state transitions. Notwithstanding, NMR structures of metalloproteins deposited in the PDB are under-represented and NMR studies exploring paramagnetic states are a minute fraction of the overall database content. This state of affairs...

Paramagnetic effects in NMR for protein structures and ensembles: Studies of metalloproteins
Paramagnetic effects on the NMR spectra are known to encode information on structure, electronic properties and dynamics hardly accessible with any other technique, especially in the field of biological systems. Paramagnetism-based restraints are conveniently used for the de novo determination of protein structures, the structural refinement starting from crystallographic models, and for the determination of the internal arrangement of domains with known structures. Conformational variability...

Q Rev Biophys. 2005 May;38(2):167-219
Authors: Arnesano F, Banci L, Piccioli M
Metalloproteins represent a large share of the proteome and many of them contain paramagnetic metal ions. The knowledge, at atomic resolution, of their structure in solution is important to understand processes in which they are involved, such as electron transfer mechanisms, enzymatic reactions, metal homeostasis and metal trafficking, as well as...
