Abstract excerpt

Electron spin echo envelope modulation (ESEEM) spectroscopy was used to investigate electron-nuclear coupling to the N epsilon of the proximal histidine (F8, His93) imidazole in oxyCo(II)-substituted distal histidine (E7, His64) mutants (His-->Leu, His-->Val, His-->Gly, His-->Gln) and recombinant...
