Postcoordination oxidation by dioxygen of one of the thiolate groups in a pentadentate N(2)S(3) ligand results in an iron(III) complex with two N-carboxamido, two thiolato, and one O-sulfinato ligands (see the CAMERON representation). This novel mixed coordination is similar to that determined for the inactive form of the nitrile hydratase from Rhodococcus sp. N-771, but differs by the O versus S binding of the sulfinato ligand.
在一个五齿N(2)S(3)配体中,其中一个硫醇盐基团被双氧进行后配位氧化,生成一种铁(III)配合物,该配合物含有两个N-羧酰胺基、两个硫醇盐基和一个O-亚磺酸盐配体(见卡梅伦表示法)。这种新型的混合配位与来自红球菌属N-771的腈水合酶无活性形式所确定的配位相似,但不同之处在于亚磺酸盐配体的O与S配位。
