Electron-nuclear coupling to the proximal histidine in oxy cobalt-substituted distal histidine mutants of human myoglobin.

Biochemistry - 21 Jun 1994

Lee H C, Peisach J, Dou Y, Ikeda-Saito M

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 wild-type human myoglobins (Mbs). Nuclear hyperfine and nuclear quadrupole coupling constants decrease in the order:...
