pAndersonJ23115:RBS-N20bglx-terminator

N20-bglX BBa_K3866032 under control of a constitutive promoter BBa_K3505012.

Fig.1: N20-bglX under control of a constitutive promoter.


Usage and Biology

Τhis part consists of AndersonJ23115 promoter BBa_K3505012, N20-bglX BBa_K3866032 and Double Terminator BBa_K3505017. By this way, as AndersonJ23115 is a strong constitutive promoter, bglx with the N20- signal peptide is constitutively expressed. The product protein is expected to be extracellular.

Design Notes

Τhe coding sequence was domesticated . We removed BsmBI ,BsaI , BtgZI, BpiI sites in order to be compatible with GoldenBraid and MoClo. The sequence is cloned in alpha1R vector BBa_K3505008and has overhangs compatible for GoldenBraid cloning.

Experimental Use and Experience

Figure 6. Growth (OD600) of E. coli MC1061 cells transformed with N20-BglX (N20), native-peptide BglX (SP) or an empty vector (EMPTY), in a minimal M9 medium with Glucose and Cellobiose as a carbon source (2).

Conclusion

N20-bglX bacteria grow more and faster than the SP-bglX and EMPTY bacteria in a 24-hour time-frame and with cellobiose as the only carbon resource. The engineered enzyme provides an advantage in situations where cellobiose is the only abundant carbon source. Also, N20-bglX bacteria reach an exponential-like phase much quicker than the native peptide or the empty vector control bacteria, which means quicker valorization cellobiose and update of glucose by the cell.
