1.13.11.20	additional information	enzyme uses an amino acid cofactor in the active site consisting of two cross-linked residues, cysteine 93 and tyrosine 157. Formation of the Cys-Tyr cofactor requires a transition metal cofactor Fe2+ and O2. Biogenesis of the cofactor is also strictly dependent upon the presence of substrate. In the absence of the Cys-Tyr cofactor, the enzyme possesses appreciable catalytic activity. At physiologically relevant cysteine concentrations, cofactor formation increases catalytic efficiency 10-fold	Rattus norvegicus
