项目摘要
Many pathogenic bacteria use nano-machines to inject proteins into their hosts' cells to promote infection and colonisation by the bacterium. One such machine is called the Type Three Secretion System or T3SS. This application seeks to investigate the way in which bacteria select and secrete proteins by using a combination of different structural and functional methods. In particular we will study two pieces of the machine that are assembled within the bacterium which genetic evidence suggests are important for the process of selecting which proteins should be injected into the host and are also implicated in the actual process of driving injection. By using methods which allow us to "see" how these parts of the machine are constructed and complementing this with studies where we make small changes in the components from which the machines are constructed and look to see what effect this has on the function of the machinery we hope to deduce the molecular mechanisms of control. Since this machinery is only found in bacteria there is the potential that a good understanding of the T3SS will eventually lead to new antibiotics which are designed to specifically interfere with this key activity.
许多致病细菌使用纳米机器将蛋白质注入宿主细胞,以促进细菌的感染和定植。其中一个这样的机器被称为第三型分泌系统或T3SS。本应用程序旨在通过使用不同结构和功能方法的组合来研究细菌选择和分泌蛋白质的方式。特别是,我们将研究在细菌内组装的机器的两个部分,遗传证据表明,这两个部分对于选择应该将哪些蛋白质注射到宿主体内的过程很重要,并且也涉及驱动注射的实际过程。通过使用能够让我们“看到”机器的这些部件是如何构造的方法,并辅以研究,我们对构成机器的部件进行微小的改变,看看这对机器的功能有什么影响,我们希望推断出控制的分子机制。由于这种机制只存在于细菌中,因此很有可能对T3SS有一个很好的了解,最终会导致设计出专门干扰这一关键活性的新抗生素。
