- 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.
