Applications of BBa_K274120

User Reviews

Characterization by UiOslo_Norway 2019

This part was of special interest to our team. The part consists of homologs of the genes we used; crtE, crtB and crtI from Deinococcus radiodurans. BBa_K274120 has individual ribosomal binding sites for each individual enzyme. The part that we made had a single ribosomal binding site followed by all three genes in a single open reading frame. The first two genes had their stopcodons removed (see BBa_K2971004 and BBa_K2971010). Figure 1 shows the result of expressing BBa_K274120 in E.coli (BL21) for 24 hours. The red coloration in the induced pellet is caused by the presence of lycopene. The induced culture with BBa_K274120 produced significant amount of lycopene when compared to expression of BBa_K2971004 (figure 2).
