中文摘要
尿鸟苷素(uroguanylin,PUG)是肽类激素尿鸟苷素的前体。测定了PUG的高分辨X射线晶体结构。在PUG的折叠过程中,不仅正确折叠的PUG的前区和肽区之间的相互作用非常重要,而且折叠中间体中的相互作用也非常重要。此外,动力学分析的折叠过程中的PUG已进行。阐明了两种折叠中间结构在折叠过程中的重要作用。此外,还通过圆二色谱(CD)、差示扫描量热法(DSC)和光散射法分析了β-淀粉样前体蛋白在溶液中的行为。
英文摘要
Prouroguanylin (PUG) is precursor of uroguanylin that is peptide hormone. X-ray crystal structure of PUG has been determined at high resolution. In the folding process of PUG, the structure suggests that not only interactions between proregion and peptide region in the PUG that has correct folding but also those in the folding intermediates are very important. Furthermore, kinetic analysis of a folding process of PUG has been performed. It is elucidated that two folding intermediate structures are important in the folding process. In addition, behaviors of β-amyloid precursor protein in the solution were analyzed by CD, DSC and light scattering.
