MutD5 testingPiotrInoculation of MutD5 carrying: pACYC177+OmpA_Z_alpha, pACYC177+OmpA_Z_omega, pACYC177+Omp_A_omega and pACYC177+OmpA_omega_ΔA + induction using 0.25mM IPTG. 'Hunter and prey' system tests: Competition testsEmilia
Fig. 1. Results of the second competition test.1 - Insert from isolated plasmid refers to OmpA_A_Omega (Z_Alpha protein added to the medium), 2 - Insert from isolated plasmid refers to OmpA_A_Alpha (Z_Omega protein added to the medium), 3 - Insert from isolated plasmid refers to OmpA_Z_Omega (A_Alpha protein added to the medium), 4 - DNA ladder. Conclusion: cells with interacting protein survive competition! Mutagenesis of protein APawełMutagenesis of protein A was performed using 2 pairs of primers: ADelL+KpnI and ADelP (deletion of aminoacids involved in interaction with protein Z) and AMutL+KpnI and AMutP (changing of few aminoacids involved in interaction with protein Z). Mutagenesis was performed on 3 vectors: pACYClac+ompA-ΔA-omega, pACYClac+ompa-ΔA-alpha and pACYClac+ ompa-omega-ΔA. Each mutagenesis was performed using each primer at final concentration 0.1 μM, dNTPs at final concentration 0.25 μM and Walk (Pfu) polymerase (shipped by A&A Biotechnology), with 100 ng of DNA template.
