Design Notes

During ste-directed mutagenesis, the codons to be mutated were replaced with the most highly utilized codons in E. coli to prevent complications from the use of rare codons. The lacI IS sequences were analyzed for BioBrick restriction sites within the coding sequence to ensure their compatibility.

Source: The lacI IS mutants presented derive from the BioBrick holding lacI by itself (C0012). Site-directed mutagenesis was performed by PCR, subsequent DpnI digest and transformation. The following primers were used:

All lacI IS holding BioBricks were verified by sequencing.
