Temperature-dependent heme kinetics with nonexponential binding and barrier relaxation in the absence of protein conformational substates

We present temperature-dependent kinetic measurements of ultrafast diatomic ligand binding to the “bare” protoheme (L(1)-FePPIX-L(2), where L(1) = H(2)O or 2-methyl imidazole and L(2) = CO or NO). We found that the binding of CO is temperature-dependent and nonexponential over many decades in time,...
