(See below for details.) This implies that the sulphur which is not bonded to any oxygens holds a negative charge. Herrmann, T., Güntert, P., and Wüthrich, K. 2002. Ray, W.K., Zeng, G., Potters, M.B., Mansuri, A.M., and Larson, T.J. 2000. Garrett, D.S., Powers, R., Gronenborn, A.M., and Clore, G.M. It is a conjugate base of a thiosulfate(1-). (A) Comparison of ribbon diagrams for At5g66040.1; GlpE, an Str from E. coli (PDB ID 1GMX); a polysulfide-sulfur transferase (homodimer) from Wolinella Succinogenes (PDB ID 1QXN); and the catalytic domain of the human Cdc25 phosphatase (PDB ID 1C25). At the time the structure was solved, the closest structure in the Protein Data Bank (PDB) had 22% sequence identity (>70 residues) to At5g66040.1. Crystalline and gaseous thiourea dioxide adopts a structure with C 2v symmetry. The C-S bond length is more similar to that of a single bond. Protein backbone angle restraints from searching a database for chemical shift and sequence homology. Identification and characterization of single-domain thiosulfate sulfurtransferases from, Bauer, M., Dietrich, C., Nowak, K., Sierralta, W.D., and Papenbrock, J. 2001. \ce{Na} & 7 & 0.86 \\\hline Because two other Arabidopsis Strs were also shown to be localized in plastids, a putative role in iron-sulfur cluster biosynthesis was suggested, similar to that of plastidic NifS-like Cys desulfhydrase (Leon et al. It has also been proposed that Lys-13 and Arg-321 (both basic residues) participate in DNA cleavage [ 32 , 33 ] and three acidic residues Asp-111, ASP-113, and Glu-115 coordinate with Mg 2+ [ 34 ]. Draw the Lewis structure of the major resonance form of the thiosulfate ion, S2O3 2-. Two distance restraints of 1.9 Å and 2.9 Å per involved pair of residues were used to represent hydrogen bonds for HN-O and N-O, respectively (Wüthrich 1986). Protein NMR structure determination with automated NOE assignment using the new software CANDID and the torsion angle dynamics algorithm DYANA. One possible (and more accurate) Lewis structure is therefore: The 15N T2 measurement suggests some mobility in this β-hairpin (Fig. Thiosulfate sind Derivate der im freien Zustand unbeständigen Thioschwefelsäure H2S2O3. These residues, buried in the hydrophobic core, form a hydrogen-bonded salt bridge in all known rhodanese and Cdc25 phosphatase structures and clearly contribute to fold stability. Structural and functional insights into thiosulfate oxidation 1 Abbreviations: acc, acceptor; AvTsdA, acc, acceptor; AvTsdA, Thirdly, https://chemistry.stackexchange.com/questions/55112/what-is-the-correct-structure-of-sodium-thiosulfate/79048#79048, https://chemistry.stackexchange.com/questions/55112/what-is-the-correct-structure-of-sodium-thiosulfate/55114#55114. $\ce{S=O}$ bonds are shorter implying a primarily double bond character. This structure exhibits a unique structural feature: an additional mobile β-hairpin with putative functional role in binding a specific substrate. Other important members of the Str family are 3-mercaptopyruvate sulfurtransferases (3-MSTs), which transfer sulfur from mercaptopyruvate to cyanide. First Orgo Made Easy video of Fall 2015! Protein Sci. Prasad, S. M.; Rani, A.; Structure of a new sodium thiosulfate hydrate. (B) The VAST domain alignment of the above structures, with the active cysteine highlighted.
