Figure 1. Activity of 22nt SL addition domain swap mutants prepared in the BmRPL13 backbone.
Replacement mutants were prepared and tested for promoter activity in the transfection assay as described in Section 2. Columns represent means, and error bars standard deviations, of six independent transfections. Columns with identical patterns represent activities produced by RP wild type promoters and their corresponding 22nt replacement mutants. Columns highlighted with asterisks indicate replacement mutants whose activity differed significantly from that of the corresponding wild type promoter (p < 0.05).
