X-ray structure of E. coli Tus protein in complex with a 15-bp Ter-containing DNA. The protein is drawn in ribbon form colored in rainbow order from its N-terminus (blue) to its C-terminus (red). The DNA is shown in stick form with C gray, N blue, O red, and P orange and with successive P atoms in the same strand joined by orange rods.
