FIGURE 6.
Normalized P(log k) rate spectra for CO (top) and O2 (bottom) rebinding with SW Mb at pH 7.3 in the absence /presence of xenon at selected temperatures. Only a few xenon pressures are shown for the readability of the figure. Each curve represents an averaged P(log k) obtained by global analysis according to three Gaussian components of three to four experiments performed at constant xenon pressure (see details in the text). The xenon pressures were 0 (solid line), 2 (dashed line), 3 (dash-dot-dash line), 5 (dash-dot dot dot-dash line), and 15 (dotted line) atm of xenon. S is the bimolecular rebinding from the solvent. All other bands correspond to geminate processes.
