Figure 1. — The salt dependence of binding constants, K^a, (salt plots). (a) The SS HMG box from hSRY binding to its optimal target DNA (DNA^Sox) and to three other duplexes of lower affinity, one containing just a central –ATAT– sequence (DNA^AT). (b) The bZIP homodimer from yeast GCN4 binding to the AP1 (–ATGACTCAT–) and ATF/CREB (–ATGACGTCAT–) target sequences. (c) The HMG box from mLEF-1 (Lef86) and its truncated form lacking the basic C-terminal tail (Lef79) binding to DNA^Lef (–TTCAAA–) the optimal target and to DNA^Sry (–CACAAA–) a sub-optimal sequence. (d) The NSS HMG box from Drosophila HMG-D (D-100) and its truncated form (D74) lacking the basic C-terminal tail binding to DNA^Lef. Data taken from Refs (11,12,17).
