FITC can inhibit the antimonite-stimulated ATPase activity of ArsA and a combination of ATP and antimonite can completely protect ArsA from the inactivation of FITC. The Lys residue in the glycine-rich loop in ArsA is possibly one of the sites for FITC modification. Antimonite can induce the fluorescence resonance energy transfer between FITC and TRITC that separately labeled on different ArsA molecules.

研究还发现FITC对ArsA的ATP酶活性有抑制作用，ATP和SbO〓与ArsA的结合完全拮抗这种抑制，说明ATP和SbO〓与ArsA的结合能够引起ArsA产生一种完全不同于它们单独与其结合时的构象变化，从而使ArsA上FITC的修饰位点变得不易接近，同时ATP结合位点内的Lys可能是FITC在ArsA上的结合位点之一。

Ringel realized positive parts of semisimple Lie algebras in the framework of Ringel-Hall algebras. The main result of this thesis is to build a geometric and topological model over triangulated categories such as derived categories and stable module categories of repetitive algebras. We defines a Lie bracket by Euler characteristics of constructible subsets and thus realizes infinite dimensional Lie algebras of various types with non-degenerated bilinear form.

In this paper, the stress and strain fields of lithosphere in Himalayan Western Syntaxis orogenic belt and its adjacent areas since 10Ma are investigated through using the 3-D finite-element simulation, and deformation and evolution process in former 2Ma are simulated with different rheological parameters and rheological structure. Studies on functions in simulation process of different viscosity parameters, constitutive relation and changes of initial curst thickness show below results:(1) When various viscoelastic models are adopted, the selection of the coefficient of viscosity in the Western Syntaxis area has important influence on the its uplifts and evolutions. The computational results show that the viscosity in the Western Syntaxis area should be smaller than 1023Pa·s;(2) When the elastic model is adopted in relatively rigid Tarim basin, obvious changes are induced to the stress and strain fields of the whole Western Syntaxis area;(3) The existence of mechanical property stable block doesn′t make the propagation of the stress field show obvious decoupling phenomenon.
