Figure 8From: Characterization of the TnsD-attTn7 complex that promotes site-specific insertion of Tn7DNA model of attTn7. A model of the attachment site, showing the minimum attTn7 site region required for TnsD binding in green, important bases (of one strand) in purple, unimportant sequence in gray, and the target duplication site in red. Phosphates are marked for clarity, although binding is probably dependent on base interactions, not sugar-backbone interactions.Back to article page
