iron-sulfur centre | K-edge X-ray absorption spectroscopy is used to monitor the structural changes of their Fe sites in the irreversible [2Fe-2S] cluster degradation process. Regardless of the differences in the cluster-ligating cysteine motifs and the XAS-detectable [2Fe-2S]2+ cluster environments, a complete reductive breakdown of the [2Fe-2S] clusters results in the appearance of a new Fourier transform peak at about 3.3 A with a concomitant loss of the Fe-Fe interaction at ca. 2.7 A for both proteins. The results suggest that a biological [2Fe-2S] cluster breakdown under reducing conditions generally releases Fe2+ from the polypeptide chain into the aqueous solution, and the Fe2+ might then be recruited as a secondary ferrous iron source for de novo biosynthesis and/or regulation of iron-binding enzymes in the cellular system | Sulfurisphaera tokodaii | |
[2Fe-2S]-center | the [2Fe-2S] cluster in SdhB-N and center C in SdhC are two succinate reducible high-potential centers detected in the archaeal succinate:caldariellaquinone oxidoreductase complex that differ in their arrangements of the cluster-binding cysteine motifs and the local cluster surroundings. a biological [2Fe-2S] cluster breakdown under reducing conditions generally releases Fe2+ from the polypeptide chain into the aqueous solution, and the Fe2+ might then be recruited as a secondary ferrous iron source for de noVo biosynthesis and/or regulation of iron-binding enzymes in the cellular system | Sulfurisphaera tokodaii |
