Proposed assembly pathway for the excision reaction. One rotating dimer could bind to each end of the element (specific binding sites in green), after which the two DNA-bound dimers would dock together to form an active tetramer. Note that the tetramers shown here and in Figure 5b can be interconverted by rotating their right halves by 180°.
