Frontispiz: Synthesis of a Nitrogenase P N ‐Cluster Model with [Fe 8 S 7 (μ‐S thiolate ) 2 ] Core from the All‐Ferric [Fe 4 S 4 (S thiolate ) 4 ] Cubane Synthon

1 FeoC from Klebsiella pneumoniae contains a [ 4 Fe - 4 S ] 2 cluster

19 Iron is essential for pathogen survival, virulence, and colonization. Feo is suggested to function as 20 the ferrous iron (Fe) transporter. The enterobacterial Feo system is composed of 3 proteins: FeoB is 21 the indispensable component and is a large membrane protein likely to function as a permease; FeoA is 22 a small src-homology 3 (SH3) domain protein that interacts with FeoB; FeoC is a ...

( S * ) - 2 , 7 , 8 - Trihydroxychroman - 4 - one

Reticumanone (1), a new chromanone, isolated from the leaves of Cinnamomum reticulatum Hay (Lauraceae), has been characterized as (S*)-2,7,8-trihydroxychroman-4-one, by means of spectroscopic methods.

Bis{μ-[4-(1,3-benzothia­zol-2-yl)phen­yl]methane­thiol­ato-κ4 S,S′:S,S′}bis­[tricarbonyl­iron(I)](Fe—Fe)

The title compound, [Fe(2)(C(14)H(10)NS(2))(2)(CO)(6)], was synthesized as a structural and biochemical model for the active site of [FeFe]-hydrogenase. The bond lengths (Fe-Fe, Fe-S and Fe-C) and angles (C-Fe-Fe and Fe-S-Fe) are within expected ranges. The S⋯S distance [2.9069 (12) Å] and the dihedral angle between two Fe-S-Fe planes [78.5 (3)°] of the butterfly-shaped Fe(2)S(2) core are enlar...

Electronic structure and fragmentation properties of [ Fe 4 S 4 ( SEt ) 4 − x ( SSEt ) x ] 2 −

A limited exposure of (n-Bu4N)2[Fe4S4(SEt)4] solutions in acetonitrile to air was found to produce a new series of [4Fe–4S] cluster complexes, Fe4S4(SEt)4−x(SSEt)x]2− (x= 1–4), with the original –SEt ligands substituted by –SSEt di-sulfide ligands, which were formed due to partial ecomposition of the [4Fe–4S] core in parent [Fe4S4(SEt)4]2−. The products were first observed in the experiments wi...
