In order to overexpress foreign genes in the cyanobacteria, the intrinsic promoter of Rubisco large subunit (PrbcL) was chosen as the target for vector construction, which is retrieved from pBR322 in our experiment. PrbcL regulates the expression of the most abundant proteins in photosynthetic species and has been proven to have a high activity to express foreign genes, so we choose PrbcL as the promoter of our pigment gene. To insert PrbcL with EcoR1 and Pst1 cutting sites, we use site-directed mutagenesis to remove Pst1 cutting site in PrbcL nucleotide sequence.
