"Coarse-grained molecular dynamics simulations of base-pair mismatch recognition protein MutS sliding along DNA"

【Significance】
The mismatch recognition protein MutS should search a DNA base-pair mismatch from millions of base-pairs. Previous studies suggested that the protein slides along DNA in rotation-coupled and uncoupled manners depending on bound nucleotide states. However, detailed structural dynamics of bacterial MutS during sliding remains unclear. Our coarse-grained molecular dynamics simulations elucidated that MutS slides along DNA grooves with different frequency of groove-crossing events depending on the nucleotide state. The simulations revealed structural dynamics details of bacterial MutS sliding along DNA in unprecedented resolution.
