(A) Representative EMSA showing the ssDNA binding activity of A3G in reactions in which Vif-derived peptides were first incubated 15 minutes with ssDNA and then A3G was added for an additional 15 minute incubation period, followed by native gel fractionation and imaging to detect free ssDNA (lower band) and ssDNA/A3G complexes (upper band).
