Design Notes
The Wild type Cas3 gene has unwanted EcoRI, XbaI and PstI restriction sites inside the gene.
These restriction sites were mutated to make this gene biobrick compatible. First multiple mutagenesis attempt was not fully successful, because restriction analysis of mutated plasmids showed, that only two out of three restriction sites were mutated.
Later we mutagenised the Mutant#1 plasmid, for the third PstI restriction using the same procedure as before. After plasmid restriction analysis (Figure 2) we had many successfully mutated plasmid (all except mutated plasmid #1), which later were sequenced and confirmed.
