“…The nickel ions may form Mo-Ni-S clusters similar to Mo-Cu-S clusters observed in copper poisoning [80] and possibly affect the interaction between D1 anaerobic and bis -MGD. Such Mo-Ni-Cu clusters are known in small molecule literature [81] and have also been reported in complexes containing Mo bound with a dithiolene ligand [82]. …”

Molybdenum is an essential nutrient for metabolism in plant, bacteria, and animals. Molybdoenzymes are involved in nitrogen assimilation and oxidoreductive detoxification, and bioconversion reactions of environmental, industrial, and pharmaceutical interest. Molybdoenzymes contain a molybdenum cofactor (Moco), which is a pyranopterin heterocyclic compound that binds a molybdenum atom via a dithiolene group. Because Moco is a large and complex compound deeply buried within the protein, molybdoenzymes are accompanied by private chaperone proteins responsible for the cofactor’s insertion into the enzyme and the enzyme’s maturation. An efficient recombinant expression and purification of both Moco-free and Moco-containing molybdoenzymes and their chaperones is of paramount importance for fundamental and applied research related to molybdoenzymes. In this work, we focused on a D1 protein annotated as a chaperone of steroid C25 dehydrogenase (S25DH) from Sterolibacterium denitrificans Chol-1S. The D1 protein is presumably involved in the maturation of S25DH engaged in oxygen-independent oxidation of sterols. As this chaperone is thought to be a crucial element that ensures the insertion of Moco into the enzyme and consequently, proper folding of S25DH optimization of the chaperon’s expression is the first step toward the development of recombinant expression and purification methods for S25DH. We have identified common E. coli strains and conditions for both expression and purification that allow us to selectively produce Moco-containing and Moco-free chaperones. We have also characterized the Moco-containing chaperone by EXAFS and HPLC analysis and identified conditions that stabilize both forms of the protein. The protocols presented here are efficient and result in protein quantities sufficient for biochemical studies.

“…Another example of a tetratelluro metallate complex is [(Cp′ 2 Nb) 2 WTe 4 · W(CO) 4 ],6 in which a central WTe 4 tetrahedron is surrounded by two niobocene fragments. Interestingly, tetrathionickelates like [Ni(MoS 4 ) 2 ]11 and [Ni(WS 4 ) 2 ]1 prefer a square‐planar arrangement of the sulfur ligands around Ni 2+ .…”
