Oxalate oxidase (EC 1.2.3.4) catalyses the conversion of oxalate and dioxygen into CO2 and H2O2. The barley (Hordeum vulgare) seedling root enzyme was purified to homogeneity and shown by metal analysis and EPR spectroscopy to contain Mn(II) at up to 0.80 atom per subunit. The involvement of Mn and neither flavin, Cu nor Fe in the direct conversion of dioxygen to H2O2 makes oxalate oxidase unique. A model of the active site of the holoenzyme based on a homology model of the apoenzyme is proposed.

Using pulsed EPR spectroscopy and isotopic labeling we demonstrate that reaction centers of Chloracidobacterium thermophilum have an unusual primary donor that is a dimer of Zn-bacteriochlorophyll aP′ molecules.
