Mechanism of replication termination in E. coli. (A) Schematic of the E. coli chromosome showing the approximate location of ter sites relative to oriC. Arrowheads indicate the permitted direction of replisome progression. Adapted from Duggin et al., 2008. (B) Mechanism of replisome trapping in the terminus region by Tus-ter. Just two ter sites are shown for clarity but the same mechanism can operate at any ter site. (C) Resolution of DNA structures following replisome convergence during termination.
