Inhibition of attP × attB recombination by gp3: differential effects on Int and Int(E449K). (A B). The data shown here correspond to TPM assays in which Int or Int(E449K) plus gp3 were added to the attP-attB (head-to-tail) substrate (see Supplementary Figure S3). The relative abundance of the individual complexes and the BM amplitude distributions of the WS complexes are arranged as in Figure 3.
