  1. Ribbon representation of the Proteus mirabilis catalase complex with NADPH (PDB code 1CAF). ß­Barrel domain = green; all­alpha domain = cyan.
  2. Active site structure: haem; distal His­54 and Asn­127 (residues involved in H2O2 binding); Tyr­337 (proximal haem iron ligand) and His­341; two water molecules (O atoms only) [1, 2].
All drawings were produced by using the program MOLSCRIPT [3].
