Abstract
Several research teams have reported detection and characterization of various apomyoglobin intermediate states different in their accumulation mode, thus putting a natural question as to proportions of these intermediates. The current report presents spectral properties of sperm whale apomyoglobin studied over a wide range of conditions with the use of circular dichroism and fluorescence techniques. Based on the experimental data, a diagram of apomyoglobin conformational states has been constructed. It shows that though induced by various denaturants, all the observed intermediates belong to one and the same area in the diagram.
