Abstract:

Human adult (HbA) and foetal (HbF) haemoglobins with different subunit structures (2α2βand 2α2γ subunits, respectively) in deoxy- and carbonmonoxy-forms have been studied by Mossbauer spectroscopy at 87 K. The assumption that Mossbauer spectra of HbA and HbF should be interpreted taking into account the non-equivalence of the Fe2+electronic structure in different sub-units was made, and the Mossbauer spectra were approximated by superposition of two quadrupole split doublets with the requirement of equal areas. The differences of the quadrupole splittings related to α- and β-subunits in HbA and α- and β-subunits in HbF were in the range of 0-21-0-25 mm/s, and were in agreement with quantum chemical calculations for the Fe2+-porphyrin-imidazole complexes chosen as models of the active sites in α- and β-subunits of tetrameric HbA. © 1987 Taylor and Francis Group LLC.
