LOW SPIN FERRIC PROTEIN MODELS

我们还获得了模型低自旋铁的EXAFS数据 由Henry Jackson和Julia Kovacs教授准备的化合物 华盛顿大学化学系。这些复合体 具有具有N3S2给体集的配体，并且可以制备为二元 低自旋铁(III)络合物(一种罕见的五配位铁 (Iii)或作为三元、六配位络合物与各种 辅助配体包括叠氮化物和一氧化氮。EXAFS和 这些复合体的边缘强度正在与 氰基水合酶进一步深入了解 酶中的铁。

We have also obtained EXAFS data on model low spin ferric compounds prepared by Henry Jackson and Prof. Julia Kovacs of the Department of Chemistry, University of Washington. These complexes have a ligand with a N3S2 donor set and can be prepared as a binary low spin iron (III) complex (a rare example of five-coordinate iron (III) or as ternary, six-coordinate complexes with a variety of auxilliary ligands including azide and nitric oxide. The EXAFS and edge intensities of these complexes are being compared to those of nitrile hydratase to gain further insight into the coordination of iron in the enzyme.
