A detail comparison demonstrates that such preconditioned IbpB is distinguished from the non-preconditioned IbpB by a remarkable conformational transformation, including a significant increase in the flexibility of the N- and C-terminal regions, as well as enhanced dynamic subunit dissociation/reassociation.

我们的比较研究表明，这样的经过热休克预处理过的 IbpB蛋白与未经历过热休克条件的蛋白之间存在很大的构象上的差异，包括前者在N-和C-末端区域可曲性的明显增强，以及亚基动态分离/重结合的加强。

Amino acid mutant site A43V locates in N-terminal headpiece of represser protein which binds specifically to DNAand amino acids mutant sites S93L, S102N, G315S, Q180R, M2491, I283T all locate in the core region of represser protein which binds to IPTG.

氨基酸突变位点A43V位于阻遏蛋白氨基末端，是阻遏蛋白和操纵基因的结合区；S93L、S102N、G315S、Q180R、M249I、I283T均位于阻遏蛋白核心区，即阻遏蛋白和IPTG结合区。

Methods This study contained a total of 16 culture groups, including one group as control and 5 groups treated by 5 drugs (calcium L-threonate, sodium L-threonate, alendronate, 17β-estradiol and calcium gluconate) each at the final concentrations of 10^(-9)mol/L, 10^(-7)mol/L, 10^(-5)mo1/L respectively. After 7 days, eight bone slices of every group were stained with toluidine blue and the areas of resorptive pits were analyzed under light microscope; the concentrations of C-telopeptide of type Ⅰ collagen CT(subscript x or Crosslaps in culture supernatants were measured by ELISA.
