Webb15 mars 2024 · The Fe 2+ is coordinated to six ligands (4 pyrrole rings of the heme in a plane, one axial imidazole ring each from the proximal histidine and bonded dioxygen). The geometry of the electron clouds around the Fe 2+ is octahedral. The six d orbitals are oriented in the same x, y, and z axes direction as the heme ligands. http://gandalf.umd.edu/BCHM461/Spring02/Exam3/ex3_sol.pdf Webb26 nov. 2016 · Only in the specific case of [L] = Kd will half of the protein be bound to ligand when equilibrium is reached. The Hill equation in that link uses the simplifying assumption that all ligands bind simultaneously and that the binding sites are identical.
