dc.description.abstract | CheY is a chemotactic response regulator protein modulating the rotation direction of bacterial flagellar motors. It plays an important role in the colonization and infection of Helicobacter pylori (H. pylori), which is a common pathogen. Recently, the structure of CheY1 of H. pylori (HpCheY1) was solved, showing similarities and differences with CheY from E. coli. Here, we report 200 ns atomistic molecular dynamics (MD) simulations of HpCheY1 and two mutants. The results suggest that the surface of HpCheY1 has regions with increased affinity for Mg²⁺. In addition, wildtype HpCheY1 (WT HpCheY1) shows characteristic dynamics in helix 4, which is involved in FliM binding. This dynamics is altered in the D53A mutant and completely suppressed in the T84A mutant. The results are discussed in relation to the binding and function of HpCheY1. | en_US |
