Design Notes
Since each individual mutant (I208V and R90A) showed imrpovement on PETase catalytic activity, our design thinking is based on the hypothesis that the combination of the two mutations will further enhance the PETase catalytic activity. 6 His tag is also appended at the end of the PETase sequence for western blotting test in case we want to verify whether the protein is being successfully made or not. The entire sequence is optimized for Escherichia coli by IDT’s codon optimization tool.

Wild type PETase sequence is originally from Ideonella sakaiensis. Two mutation sites are originally designed by 2016 iGEM Tianjin team.
