The complex trapped in the active sites of the APD-4NC structure. (a) 4NC fitting the electron density. (b) 4NC binding the iron oxidized from the ferrous state to the ferric state. Hydrogen bonds and the 4NC-Fe3+ interaction are represented by dashed lines. Numbers indicate bond distances in Å. (c) The Fe-coordination sphere with overlaid ligands: intermediate, product and 4NC. The APD intermediate model is denoted with atom-indexed colours; the product ligand is in cyan and the APD-4NC model is in green.  [article HTML]
