Effective intermediate-spin iron in O(2)-transporting heme proteins
Proteins carrying an iron-porphyrin (heme) cofactor are essential for biological O(2) management. The nature of Fe-O(2) bonding in hemoproteins is debated for decades. We used energy-sampling and rapid-scan X-ray Kβ emission and K-edge absorption spectroscopy as well as quantum chemistry to determin...
