WebbThe imidazole ring of the proximal histidine is one of the axial ligands for the the Fe ion (the O2 is the other). When the Fe ion moves into the ring of the heme it therefore pulls … WebbThe F8 histidine is the 8th residue of the F helix in both α and β globin chains. This coordinate bond links the F helix to the heme, so that changes in the disposition of the …
