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, [http://partsregistry.org/Part:BBa_I51020 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

Results

  • These genes will be PCR amplified from pRL1383a in all cases except for the P1 lytic region which will be amplified from a BioBrick plasmid: pSB2K3.

Discussion

Make Parts

  • I am making the parts several different ways: 1. PCR amplification, 2. synthetic construction of overlapping oligonucleotides, 3. extraction from BioBrick Registry.

PCR Amplification of pRL1383a

  • Each of these experiments can be found at the link above. This will include amplification products from other plasmids besides pRL1383a.

Oligonucleotide Assemby

  • The experiment and results can be found on the link above under the heading: "2 Construction of OriT from RP4 using Overlapping Oligonucleotides: Attempt 1"

Extraction of BioBrick Parts from Registry

  • Some parts were extracted from BioBrick registry, the experiments and results will be included in the link above.

Ligation of Parts

  • Experiments and results found in link above.
