How can EPR spectroscopy help to unravel molecular mechanisms of flavin-dependent photoreceptors?
Frontiers in Molecular Biosciences, 2015 Electron paramagnetic resonance (EPR) spectroscopy is a well-established spectroscopic method for the examination of paramagnetic molecules. Proteins can contain paramagnetic moieties in form of stable cofactors, transiently formed intermediates, or spin

Regulation of nitric oxide signaling by formation of a distal receptor-ligand complex. [PDF]
, 2017 The binding of nitric oxide (NO) to the heme cofactor of heme-nitric oxide/oxygen binding (H-NOX) proteins can lead to the dissociation of the heme-ligating histidine residue and yield a five-coordinate nitrosyl complex, an important step for NO ...
