XANES for the 2-His-1-carboxylate motif. (a) Experimental data for human tyrosine hydroxylase in the native, lyophilized native and oxidized state (Meyer-Klaucke et al., 1996; Schünemann et al., 1999). (b) Simulations based on a small sphere for phenylalanine hydroxylases [Fe(II): 4.33 Å/Fe(III): 4.12 Å] and (c) simulations based on a larger sphere [Fe(II): 5.67 Å/Fe(III): 5.38 Å]. (d) Edge-shape simulations for Fe(II) tyrosine hydroxylase with coordination six and five. |
