Figure 3. AdRP-linked mutations decrease affinity for a random pool of ssDNA and increase the fraction bound in a filter-binding assay.
The fraction bound was determined by various amounts of IMPDH1 (shown as concentration of tetramer) incubated with a labelled pool of random ssDNA sequences as described in the Experimental section. Results are representative of three experiments, and the best fit of a simple binding model is represented by the lines (eqn 3).
