[Various physico-chemical properties of hemoglobins in representatives of different classes of vertebrates].
The level of hydrophobic property and microviscosity in central and peripheral sections of molecules of main electrophoretic fractions of hemoglobins in representatives of different classes of vertebrates has been studied by means of the methods of fluorescent spectroscopy. It has been found that central sections of hemoglobin molecules are characterized by less pronounced changes in the volume and level of hydrophobic properties and highly pronounced changes in the packing integrity as compared to peripheral sections of the protein globule. Peripheral sections of hemoglobin molecules in the mammals are characterized by higher amount of surface tyrosines and lower level of hydrophobic properties against similar indices in representatives of other classes of vertebrates. Microviscosity (packing compaction) in central sections of hemoglobin molecules decreases with a transfer from low phylogenetic groups of vertebrates to higher ones.
