Structural heterogeneity of the Fe(2+)-N epsilon (HisF8) bond in various hemoglobin and myoglobin derivatives probed by the Raman-active iron histidine stretching mode.
We have examined the Fe(2+)-N epsilon (HisF8) complex in hemoglobin A (HbA) by measuring the band profile of its Raman-active nu Fe-His stretching mode at pH 6.4, 7.0, and 8.0 using the 441-nm line of a HeCd laser. A line shape analysis revealed that the band can be decomposed into five different su...
