Analysis of nitroxide spin label motion in a protein-protein complex using multiple frequency EPR spectroscopy.
X- and W-band EPR spectra, at room and low temperatures, are reported for nitroxide spin labels attached to cysteine residues selectively introduced into two proteins, the DNase domain of colicin-E9 and its immunity protein, Im9. The dynamics of each site of attachment on the individual proteins and...
