NMR Based Structure, Function and Dynamics analysis of Ribosomal Protein S1 from Mycobacterium Tuberculosis

Abstract

WHO2016年结核病全球报告指出,结核病已成为死亡率高于艾滋病(HIV/AIDS)的全球性高危致死性疾病。随着全球耐多药结核菌株的出现和蔓延,寻找新药物靶标蛋白和研发抗结核新药已成为近些年研究的热点。抗结核一线药物吡嗪酰胺,可以将治疗周期由传统的9-12个月缩短为6个月,尽管它在临床上使用60多年,然而直到近期才发现它主要是通过其生理活性形式吡嗪酸来发挥抗菌治病功能,即:吡嗪酸通过特异性地结合核糖体蛋白MtRpsA的C端结构域,抑制tmRNA与MtRpsA相互作用,从而导致拯救受困核糖体的反式翻译过程终止,使细胞凋亡。目前,POA与MtRpsA的C端结构域相互作用的复合物晶体结构已经被解析,...Global tuberculosis report for 2016 noted that tuberculosis had hold the highest mortality than HIV/AIDS, remained one of the top 10 causes of death worldwide in 2015, while Mycobacterium tuberculosis (Mtb) is a pervasive human pathogen that causes tuberculosis (TB). Therefore, the identification of new targets in Mtb that might be inhibited to effectively kill the existing strains is now a global...学位:理学硕士院系专业:化学化工学院_物理化学学号:2052014115157
