Design Notes

Mutagenesis to remove internal EcoRI site

Cas9 for chloroplast

Sequence was codon optimized with software developed at UCL in Saul Purton's lab working on algal biotechnology. Can be found at the following link: https://www.ucl.ac.uk/algae/Genetic_engineering_tools. The sequence was additionally modified to remove all Bsa1 and BsmBI sites (illegal for phytobrick syntax) in the coding sequence and where possible the codon maintained as well as the genetic bias.

No direct source for part, need to be synthesized, sequence based on S. pyrogenes (http://www.uniprot.org/uniprot/Q99ZW2). Due to the large size of the protein, iDT synthesized part in 4 pieces which we were able to assemble through golden gate with the appropriate primers to maintain the coding sequence intact. Alternatively, Gibson could have been used for assembly.
