项目摘要
Project Summary:
Over the last two decades, enabled by progress in synchrotron radiation techniques, molecular biology
methods, and computational resources, there has been tremendous progress in determining the structure
of biomolecules that has led, in many cases, to deep structural insights. But there is a third dimension to
biological function, namely dynamics, which is, as yet, underexplored. This has created a serious blind
spot that inhibits progress towards a full understanding of macromolecular functions and biological
processes. The broad objective of this proposal is to develop and utilize computer simulations that
address this deficiency in knowledge by rigorously modeling biomolecular dynamics in order to increase
our understanding of biological processes. More specifically, we will pursue three interrelated projects.
First, we will determine how chromatin remodeling factors influence the dynamics of nucleosomes and
chromatin fibers as a means of regulating gene expression. Second, we will examine the mechanisms of
recognition and regulation by sortase enzymes, which are key virulence factors in Gram-‐positive bacteria.
Finally, we will develop computational methods that more effectively model the results of solution small
angle X-‐ray scattering (SAXS) experiments for diverse biomolecular complexes. Completion of these
studies will reveal intricate details about the relationship between the structure, function, and dynamics
of multicomponent biomolecular complexes across a vast range of time and length scales. Furthermore,
the synergy between the scientific goals, as well as the computational methods and strong experimental
collaborations in each of these projects, will foster new opportunities and areas of scientific inquiry that
the MIRA award will allow us to pursue. Overall, this work will address a series of fundamental gaps in
knowledge for critical biological processes, and will lay the foundation for future studies that will
improve the treatment and prevention of human ailments.
项目概要:
在过去的二十年里,由于同步辐射技术的进步,分子生物学
方法和计算资源,在确定结构方面取得了巨大的进展
在许多情况下,这导致了对生物分子结构的深入了解。但还有第三维,
生物功能,即动力学,这是,迄今为止,探索不足。 这造成了严重的盲目性。
这一点阻碍了对大分子功能和生物学特性的全面理解
流程. 这项建议的主要目标是开发和利用计算机模拟,
通过严格模拟生物分子动力学来解决这一知识不足,
我们对生物过程的理解。更具体地说,我们将从事三个相互关联的项目。
首先,我们将确定染色质重塑因子如何影响核小体的动力学,
染色质纤维作为调控基因表达的一种手段。其次,我们将研究
分选酶是革兰氏阳性菌中的关键毒力因子。
最后,我们将开发计算方法,更有效地模拟解决方案的结果小
针对不同生物分子复合物的角X射线散射(SAXS)实验。 完成这些
研究将揭示结构、功能和动力学之间关系的复杂细节
多组分生物分子复合物在广泛的时间和长度范围内。此外,
科学目标之间的协同作用,以及计算方法和强大的实验
在这些项目中的每一个合作,将促进新的机会和科学探究的领域,
总的来说,这项工作将解决一系列根本性的差距,
关键生物过程的知识,并将为未来的研究奠定基础,
改善人类疾病的治疗和预防。
