Abstract:
The non-haem Fe(II) and 2-oxoglutarate (2OG)-dependent oxygenases belong to a superfamily of structurally-related enzymes that play important biological roles in plants, microorganisms and animals. Structural, mechanistic and functional studies of 2OG oxygenases require efficient and effective biophysical tools. Nuclear magnetic resonance (NMR) spectroscopy is a useful tool to study this enzyme superfamily. It has been applied to obtain information about enzyme kinetics, identify and characterise 2OG oxygenase-catalysed oxidation products, elucidate the catalytic mechanism, monitor ligand binding and study protein dynamics. This review summarises the types of information that NMR spectroscopy can provide in the studies of 2OG oxygenases, highlights the advantages of the technique and describes its drawbacks.
