“…In these fits, the Debye-Waller factor for the Zn-(N,O) first-shell was not constrained to be a particular ratio with the second-and thirdshell values since static disorder in such a mixed-ligand shell is expected to result in larger relative Debye-Waller σ as # values. Calibration with Zn(imid) [40] indicated accuracies within 0n02 A H for the firstshell distances reported here.…”

The Thermoanaerobacter ethanolicus 39E adhB gene encoding the secondary-alcohol dehydrogenase (secondary ADH) was overexpressed in Escherichia coli at more than 10% of total protein. The recombinant enzyme was purified in high yield (67%) by heat-treatment at 85 degrees C and (NH4)2SO4 precipitation. Site-directed mutants (C37S, H59N, D150N, D150Eand D150C were analysed to test the peptide sequence comparison-based predictions of amino acids responsible for putative catalytic Zn binding. X-ray absorption spectroscopy confirmed the presence of a protein-bound Zn atom with ZnS1(imid)1(N,O)3 co-ordination sphere. Inductively coupled plasma atomic emission spectrometry measured 0.48 Zn atoms per wild-type secondary ADH subunit. The C37S, H59N and D150N mutant enzymes bound only 0.11, 0.13 and 0.33 Zn per subunit respectively,suggesting that these residues are involved in Zn liganding. The D150E and D150C mutants retained 0.47 and 1.2 Zn atoms per subunit, indicating that an anionic side-chain moiety at this position preserves the bound Zn. All five mutant enzymes had

“…Complexes with other transition-metal cations that are related to the structure of the title compound are not reported in the Cambridge Structural Database (Version 2020; Groom et al, 2016). For Zn and Ni, one complex is found in which the Ni cations are in a square-pyramidal coordination of four S atoms of two [S 4 ] 2À anions and charge balance is achieved by tetraethylammonium cations (Mü ller et al, 1983;(Coucouvanis et al, 1985). Similar compounds are also reported with Ni and Hg, but the tetraethylammonium cations are replaced by tetraphenylphosphonium cations (Coucouvanis et al, 1985;Mü ller et al, 1985;Bailey et al, 1991).…”

The title compound, [Mn(S4)(C8H20N4)], was accidentally obtained by the hydrothermal reaction of Mn(ClO4)2·6H2O, cyclen (cyclen = 1,4,7,10-tetraazacyclododecane) and Na3SbS4·9H2O in water at 413 K, indicating that polysulfide anions might represent intermediates in the synthesis of thiometallate compounds using Na3SbS4·9H2O as a reactant. X-ray powder diffraction proves that the sample is slightly contaminated with NaSb(OH)6 and an unknown crystalline phase. The crystal investigated was twinned with a twofold rotation axis as the twin element, and therefore a twin refinement using data in HKLF-5 format was performed. The asymmetric unit of the title compound consists of one MnII cation, one [S4]2− anion and one cyclen ligand in general positions. The MnII cation is sixfold coordinated by two cis-S atoms of the [S4]2− anions, as well as four N atoms of the cyclen ligand within an irregular coordination. The complexes are linked via pairs of N—H...S hydrogen bonds into chains, which are further linked into layers by additional N—H...S hydrogen bonding. These layers are connected into a three-dimensional network by intermolecular N—H...S and C—H...S hydrogen bonding. It is noted that only one similar complex with MnII is reported in the literature.

“…The adsorption of metal ions proceeds by complexation with the interlayer [S x ] 2À group to form polysulde complexes. 76,77 In a way, the intercalated polysulde species can act as a second host to incoming metal ions. Another important point in the IR spectra is the shi of the v(M-O) vibrations from 663 to 681-683 cm À1 aer metal adsorption (Fig.…”
