Pigment double-crossover homologous gene recombination bacbone (pPIGBACK)

Part description

The vector, pPIGBACK, is used to transform into S. elongatus PCC 7942 with the inserted pigment gene in our project. pPIGBACK contains 5’- and 3’-ends of the neutral site II (NSII), replication origin of pBR322, ampicillin resistance gene, and double terminator BBa_B0015. The strategy we chose to construct the vector is to fuse B0015 and AmpR together first. Secondly, we fused 5’- and 3’-ends of the neutral site II (NSII) with PBR322 replication origin (ORI) together. At last, we ligated two parts together. The aim of constructing this vector is to finish double-crossover homologous gene recombination in S. elongatus PCC 7942. To insert BBa_J04450 with EcoR1 and Pst1 cutting sites, we use site-directed mutagenesis to remove all Pst1 cutting sites in pPIGBACK.


Result

Figure 1 is pPIGBACK-CrtZ transformants electrophoresis result. C1~C20 represents the pPIGBACK-CrtZ transformant clone 1 to clone 20, and M represents 1 kb marker.Transformation efficiency of pPIGBACK-CrtZ is 11.4 transformants per μg DNA, and correctness is 52% (10/19), which is quite efficient because the successful rate of gene double-crossingover homologous recombination is low. See Figure 1.
