NAPHTHALENE 1,2-DIOXYGENASE WITH OXIDIZED RIESKE IRON SULPHUR CENTER SITE.
OverviewOverview
Binding of oxygen to iron is exploited in several biological and chemical, processes. Although computational and spectroscopic results have suggested, side-on binding, only end-on binding of oxygen to iron has been observed, in crystal structures. We have determined structures of naphthalene, dioxygenase that show a molecular oxygen species bound to the mononuclear, iron in a side-on fashion. In a complex with substrate and dioxygen, the, dioxygen molecule is lined up for an attack on the double bond of the, aromatic substrate. The structures reported here provide the basis for a, reaction mechanism and for the high stereospecificity of the reaction, catalyzed by naphthalene dioxygenase.
