To understand whether the new functionalities introduced into the pSB1K were suitable for subsequent experiments, we compared the growth curves of the pSB1KY-transformed yeast cells and p426-transformed ones expressing turboRFP. Two main cultures were adjusted to 1 OD in 20 ml of MV medium in flasks and, after 12 hr, their growth rates were monitored using a spectrophotometer.

From the plots of the growth rates (Figure 8) we were able to observe that the new pSB1KY performs just as well as the widely used p426 shuttle plasmid [1].

During the experiments for the creation of the SP-SUMO tag for protein production in yeast (read more about it here), we were once again able to compare the two plasmids. Both the p426 and the new pSB1KY were used to express the SP-SUMO device aminoterminally fused to the turboRFP fluorescent protein. This construct allowed the protein to be secreted in the medium and we were able to measure the development of fluorescence. The fluorescence intensity in the medium normalized over growth (expressed in nephelometric turbidity units) (Figure 9) showed that the pSB1KY is able to produce and secrete larger quantities of turboRFP. This was observed in two other experiments (data not shown) and seems to indicate that the pSB1KY allows for higher protein production.
