摘要 ：Molecular interactions between proteins and DNA play crucial roles in many fundamental biological processes, such as DNA modification and gene regulation. DNA-binding proteins encompass various degrees of binding specificity, ranging from highly specific to non-specific. How DNA-binding proteins achieve high binding specificity is still not well understood. In this talk, I will present our recent work on structural features for protein-DNA binding specificity. We investigated both the static and dynamic structural features for achieving high degree of protein-DNA binding specificity. Specifically, we carried out a comparative analysis of protein-DNA complexes with different degrees of binding specificity. We also investigated the role of protein flexibility in protein-DNA binding specificity by comparative molecular dynamics (MD) simulations. Our results show the important roles of protein flexibility and dynamic properties in protein-DNA binding specificity.
