Mechanism of ligand binding to hemes and hemoproteins. A high-pressure study

The effect of pressure on the recombination kinetics of small ligands binding to sperm whale myoglobin, protoheme dimethyl ester, and monochelated protoheme was studied with use of laser flash photolysis. The results are discussed in terms of the previously proposed three- and four-state reaction sc...

Beschreibung
Zusammenfassung:The effect of pressure on the recombination kinetics of small ligands binding to sperm whale myoglobin, protoheme dimethyl ester, and monochelated protoheme was studied with use of laser flash photolysis. The results are discussed in terms of the previously proposed three- and four-state reaction schemes for model hemes and myoglobin, respectively.
