ESCHERICHIA COLI REPLICATION TERMINATOR PROTEIN (TUS) COMPLEXED WITH DNA
OverviewOverview
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.
