Utilization of Nitric Oxide as a Paramagnetic Probe of the Molecular Oxygen Binding Site of Metalloenzymes
The paramagnetism of many nitrosylated complexes of metalloproteins has led to numerous but limited studies by EPR spectroscopy since the early seventies. Spectral analysis can, in the best of cases,
Electron Paramagnetic Resonance in the Study of Binuclear Centres of Copper Proteins
Metalloproteins often use binuclear metal centres to perform important biological functions. This is the case of electron transfer proteins, such as ferredoxins, oxygen carriers, such as hemerythrin

The reaction of nitrogen monoxide and of nitrite with deoxyhaemocyanin and methaemocyanin of Helix pomatia.
Under strictly anaerobic conditions deoxyhaemOCyanin and methaemocyanin, treated with NO, gave the same derivative as shown by circular dichroism and EPR spectra.

Electron spin resonance studies of copper(II) in haemocyanin, its chelates with (±)-mercaptosuccinic acid, and some related systems
E.s.r. measurements have been made on haemocyanin samples derived from the South Australian crayfish, Jasus lalandii. In order to assist in the interpretation of the results the e.s.r. spectra given
