Title: Catalytic reduction of nitric oxide by the siderophore ferrioxamine B

Abstract

The reduction of nitrogen oxides by transition metal complexes has been an area of intense research due to importance in the environment and physiology. We present a unique catalytic system in which the iron siderophore ferrioxamine B (E{sub l/2}(Fe(III/II))=-0.76 V v SSCE) facilitate, the reduction of nitric oxide at potentials as low as -0.6 V v. SSCE. The reduction proceeds through a rapidly formed iron-containing intermediate that can be observed in the visible spectrum. This absorbance exhibits a strong 1000 cm{sup -1} catalytic cycle. progression at room temperature. This species is the resting state of the catalytic cycle. The differential binding constant of the siderophore ligand for Fe(III) over Fe(II) provides part of the driving force in the catalytic cycle.
