Abstract

The oxidized structure as [Mo(super IV)(OH(sub x))(S.Cys)(S2pd)(sub 2)] (x=1or 2) was established by X-ray crystallography. It is demonstrated that the nitrate is first bound to the molybdenum of the reduced cofactor with the formation of an enzyme substrate complex followed by the essential oxotransfer and the elimination of nitrite ion with the formation of oxidized oxomolybdenum cofactor [Mo(super IV)(O)(S.Cys)(S2pd)(sub 2)].

Abstract

The article focuses on the chemistry of [Et4N][MoIV(SPh)(PPh3)(mnt)2] as an functional analogue of the active site for dissimilatory nitrate reductase of Desulfovibrio desulfuricans. It also reveals that the substitution of thiolate by chloride yielded structurally similar complex of [Et4N][MoIV(Cl)(PPh3)(mnt)2].
