1. Ribbon representation of the Pseudomonas aeruginosa protocatechuate 3,4­dioxygenase ß dimer (PDB code 2PCD, chains A and M). Chain A ( subunit) = violet; chain M (ß subunit) = green.
2. Mononuclear iron centre and its ligands. All the iron ligand residues are provided by the ß subunit. Note that in 2PCD amino acid numbering of the ß subunits begins with 301, thus Tyr­408, Tyr­447, His­460 and His­462 correspond to the ß subunit residues Tyr­108, Tyr­147, His­160 and His­162.
