英文摘要
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.
