The document describes the structure of a complex between the Escherichia coli replication terminator protein (TUS) and 13 base pairs of double-stranded DNA. The TUS protein locks the DNA in a bent conformation with an unstretched length of 4.135 nm. The whole TUS-DNA complex is approximately 5.2 nm by 7 nm by 4.78 nm in size and shows the TUS protein (colored pink, orange, purple and white) binding along the DNA in the major and minor grooves.
