Abstract

The Tus-Ter protein-DNA complex of Escherichia coli blocks progression of DNA replication from only one direction at the replication terminus. As the replication fork helicase unwinds one side of Ter, a conserved cytosine flips out of the duplex and binds to Tus, thereby creating a locked complex that blocks the advancing helicase. © 2006 Elsevier Ltd.
