The iron coordination in native, Fe(II), lipoxygenase has been studied by Extended X-Ray Absorption Fine Structure (EXAFS). The ligands are 6 +/- 1 nitrogen and/or oxygen ligands at 2.05-2.09 A, with a maximum variance of 0.09 A. The number of imidazole ligands is estimated at 4 +/- 1 using multiple scattering simulations. The remaining ligands are proposed to be carboxylate oxygens.
