Tetrathionate hydrolase (4THase) from the iron- and sulfur-oxidizing bacterium ${it Acidithiobacillus ferrooxidans}$ catalyses the disproportionate hydrolysis of tetrathionate to elemental sulfur, thiosulfate and sulfate. The gene encoding 4THase (${it Af-tth}$) was expressed as inclusion bodies in recombinant ${it Escherichia coli}$. Recombinant ${it Af}$-Tth was activated by refolding under acidic conditions and was then purified to homogeneity. The recombinant protein was crystallized in 20 m${it M}$ glycine buffer pH 10 containing 50 m${it M}$ sodium chloride and 33%(${it v/v}$) PEG 1000 using the hanging-drop vapour-diffusion method. The crystal was a hexagonal cylinder with dimensions of 0.2 $$times$$ 0.05 $$times$$ 0.05 mm. X-ray crystallographic analysis showed that the crystal diffracted to 2.15 ${AA}$ resolution and belongs to space group ${it P}$3$$_{1}$$ or ${it P}$3$$_{2}$$, with unit-cell parameters ${it a}$ = ${it b}$ = 92.1, ${it c}$ = 232.6 ${AA}$.

Investigation on collapse mechanism of super-deep vertical shaft

Sakurai, Shunsuke*; Shimizu, Norikazu*; Akutagawa, Shinichi*; Yoshida, Hidenori*; Sato, Toshinori; Yamachi, Hiroshi*

Doboku Gakkai Rombunshu, F, 62(4), p.662 - 673, 2006/12

Recent interests in the development of deep underground facilities have been drawing significant attention for the importance of vertical shafts at great depth. However, due to shrinkage of domestic coal production, any deep shafts in the order of 1000 m have not been constructed in more than 20 years. For the purposes of technical transfer and establishment of fundamentals for rational design method of vertical shafts, intensive literature review and interviews to engineers with relevant experiences were conducted. As the results, there are two distinctive modes of failure mechanism originated by the common cause, that is "takanuke" and lining failure due to unexpected earth pressure.
