Structural and biochemical characterization of iminodiacetate oxidase from Chelativorans sp. BNC1.

Ethylenediaminetetraacetate (EDTA) is the most abundant organic pollutant in surface water because of its extensive usage and the recalcitrance of stable metal-EDTA complexes. A few bacteria including Chelativorans sp. BNC1 can degrade EDTA with a monooxygenase to ethylenediaminediacetate (EDDA) and then use iminodiacetate oxidase (IdaA) to further degrade EDDA into ethylenediamine in a two-step oxidation.
