PubMed Abstract: The crystal structure of the Escherichia coli replication-terminator protein (Tus) bound to terminus-site (Ter) DNA has been determined at 2.7 A resolution. The Tus protein folds into a previously undescribed architecture divided into two domains by a central basic cleft. This cleft accommodates locally deformed B-form Ter DNA and makes extensive contacts with the major groove, mainly through two interdomain beta-strands. The unusual structural features of this complex may explain how the replication fork is halted in only one direction.
