Beta-subunit of Qbeta replicase holoenzyme

Characterlization

Whole cell lysate, supernatant and precipitations of cells with different constructs are loaded into SDS-PAGE gels. Figure 3 shows the electrophoresis results of samples that transformed with three different constructs: 1. pETDuet-1-Rep (Expressing β subunit alone) 2. pACYC-TS-TU (co-expressing EF-Ts and EF-Tu) 3. pACYC-TU (Expressing EF-Tu alone) It can be clearly observed that, unpon inducement of IPTG, pETDuet-1-Rep doesn't lead to the abundant production of β subunit. None of the three lanes of cells that transformed with pETDuet-1-Rep display a detectable band at 65.6 kDa, the size of β subunit. The cells that transformed with pACYC-TS-TU and pACYC-TU, however, shows unambiguous production of EF-Ts (position indicated by red arrow) and EF-Tu (position indicated by orange arrow).
