The CBD sequence is retrieved from the GenBank. We modified its codon usage preference from eukaryotic to prokaryotic expression. We designed a plasmid with restriction site XbaI, promoter BBa_J23101, rbs, and restriction site BamHI, sent it for synthesis at Beijing Zi Xi Biotech, and the fragment we got was digested by enzymes. The result DNA and our PBP5 generator (BBa_K1979003) are digested by XbaI and BamHI, after which they are purified and ligated, and become our new construct.
