Construction of Broad-Host-Range Expression Vector from pRL1383a and Other Parts
This expression vector will pull parts from the RSF1010 derived broad-host-range plasmid pRL1383a, the self-transmissible plasmid RP4 and also from available BioBrick parts. These parts will be obtained through either PCR amplification from the original DNA, by synthetically constructing them as outlined in Silver's method for overlapping oligonucleotides, and finally through extraction from the BioBrick parts registry.
The obtained parts will then be maintained on seperate plasmids then later compiled onto the BioBrick Base Vector, BBa_I51020. The mobility of this vector will be tested by first transforming into E. coli then conjugatively transferred to SynechocystisPCC6803, followed by the final test of cloning in genes and testing their expression in both E. coli and SynechocystisPCC6803.
Design
Methods
- Design Primers
- Design overlapping oligonucleotides
- Selection of additional BioBrick parts
- Lay-out of the new vector
