    The ups and downs of Feher-style ENDOR

    A new transient variation of the “Feher-style” electron-nuclear double resonance (ENDOR) method is examined. In this technique, the passage-mode electron paramagnetic resonance (EPR) signal is monitored follow...

    Investigation by EPR and ENDOR spectroscopy of the novel 4Fe ferredoxin fromPyrococcus furiosus

    The hyperthermophilic archaeonPyrococcus furiosus contains a four-Fe ferredoxin (Pf- Fd) that differs from most other 4Fe-Fd’s in that its [Fe4S4] cluster is anchored to protein by only three cysteinyl residues.P...

    CO Binding to and Metal-Ion Valencies of the Femo-Cofactor in CO-Inhibited Nitrogenase

    When Mo-nitrogenase undergoes enzymatic turnover in the presence of CO, the S = 3/2 cofactor signal is replaced by two different S = 1/2 signals, one (lo-CO; g = 2.09, 1.97, 1.93) at low pressure (0.08 atm) and t...

    Endor of Metalloproteins at X-Band and Q-Band Microwave Frequencies

    One of the common difficulties in the ENDOR studies of many metalloproteins is that the resonances of non-protonic elements in the site of interest frequently are obscured by the more intense proton ENDOR sign...
