Figure 5. DNA binding regions of VapB10 in the PvapBC10 promoter.
(A) Schematic representation of the DNA fragments used in EMSAs. The numbers indicate the ends of the fragments relative to the transcriptional start site. + or − indicates that VapB10 binds to the DNA fragment or not. (B) EMSAs of VapB10 binding to the different regions of the promoter PvapBC10. The DNA fragments P1, P2 and P3 were PCR amplified with the primer pairs PvapBC10-E3/PvapBC10-E4, PvapBC10-E5/PvapBC10-E6 and PvapBC10-E7/PvapBC10-E2. The labeled fragment P1 (lanes 1-5), P2 (lanes 6-10) and P3 (lanes 11-15) were incubated with increasing concentrations of VapB10 (see the Figure 5 legend for further details), respectively.
