IN mutant DNA strand transfer activities. (A) Scanned gel images show the migration positions of preprocessed substrate (S) DNA as well as the integration products (IP) of DNA strand transfer. IN was omitted from the reactions loaded in lanes 1 and 16; the remaining lanes contained the indicated IN proteins. (B) Mean DNA strand transfer activities ± SEM for two independent experiments plotted as percentage of WT IN activity.
