FIG. 3.

(A) Model for transient DBP-Pol interaction via the displaced strand. On the left, DBP is able to contact Pol via the displaced strand and thereby stimulates the initiation. On the right, DBP is unable to contact Pol when the ssDNA gap becomes too large, such as in TDΔ20; hence, no stimulation of initiation can be observed. (B) Initiation assay on 0.3 pmol of origin-containing templates. Assay conditions are as described in the legends to Fig. 1 and 2. The fold stimulation of initiation by DBP is shown.
