OneProt
The pTet expression system and limonene synthase construct is evolved around one thing: the OneProt.
We have made the pTet-OneProt construct in order for us to synthesize a nutritional protein with the
correct ratio of essential amino acids and the correct ratio between essential and non-essential
amino acids. The device is found as Bba_K1475000.
The protein is self-designed, so we wanted to test if the protein were expressed in E. coli K12 MG1655, by
the use of Western blotting. The western blot was blottet with E. coli K12 MG1655 wild-type and E. coli
expressing OneProt at different OD measures.
Figure 1: Western blot showing E. coli wild-type and E. coli expressing OneProt at OD at 0.3, 0.8, 1.8 and an overnight
culture. The membrane has been exposed for 10 minutes.
The protein has a 3xFLAG tag and since bonds are showing, OneProt is expressed. However, from this
western blot, we cannot see if the protein has been cut, just that it is expressed.
