to 2.1 A resolution. Heme P460 contains two covalent cross-links between the porphyrin and a Tyr residue. When purified from source, an unknown physiological HAO binding partner NE1300 is present within the crystal. Protein NE1300 may play a structural role in the ternary complex with cytochrome c554, the physiological electron acceptor of the enzyme
