Project Summary The long-term goal of this project is a detailed mechanistic understanding of the autoprocessing mechanism by which viral proteases cut themselves out of precursor polyproteins. Autoprocessing is critical to the life cycle of many viruses, but is poorly understood in part because the structure of protease in polyproteins is highly dynamic. In Aim 1, we will determine the potency of a panel of inhibitors for autoprocessing of HIV-1 protease. The results from this aim will provide a guide to understand the physical properties at different positions on inhibitors that govern binding. In Aim 2, we will use deep mutational scanning to determine how all possible point mutations in protease impact autoprocessing efficiency. The results from this aim will determine the physical requirements at each position in protease for autoprocessing. Together, these aims will provide a detailed understanding of the physical underpinnings of autoprocessing by HIV-1 protease.

项目摘要 这个项目的长期目标是对自动处理的详细机制有一个了解 病毒蛋白酶将自身从前体多聚蛋白中切割出来的机制。自动处理是 对许多病毒的生命周期至关重要，但人们对它的了解很少，部分原因是它的结构 多聚蛋白中的蛋白酶是高度动态的。在目标1中，我们将确定一组 HIV-1蛋白酶自动加工的抑制剂。这一目标的结果将为以下方面提供指导： 了解控制结合的抑制剂上不同位置的物理性质。在目标2中， 将使用深度突变扫描来确定蛋白酶中所有可能的点突变如何影响 自动处理效率这一目标的结果将决定每个国家的物质要求。 在蛋白酶中的位置进行自动处理。总之，这些目标将提供一个详细的了解， HIV-1蛋白酶自动加工的物理基础。
