Abstract:

Normal human adult, rabbit and pig oxyhemoglobins in frozen red blood cell solutions were studied using Mossbauer spectroscopy with a high velocity resolution. Spectra were analyzed using two models with and without accounting for the heme iron electronic structure non-equivalence in alpha- and beta-subunits of tetrameric hemoglobins. The observed differences of Mossbauer hyperfine parameters were related to structural variations in human, rabbit and pig oxyhemoglobins as well as to the differences in ligand binding affinities of these proteins.
