Design Notes

Design Notes of GSH (BBa_K2571005)

Our circuit consists of prefix, a strong promoter (J23100), RBS (B0034), GSH as protein coding region, double terminator (B0015) and suffix. This part enables our E. coli KO11 strain to overexpress oxidised Glutathione to reduce oxidative stress, increasing its lifespan. (Lu, 2013) Our construct is inserted into pSB1C3 and delivered to the Registry.


Circuit design of BBa_K2571005. Our construct includes a strong promoter,RBS, GSH and double terminator.


In order to make our gene compatible with RFC 10, 25 and 1000, we reconstructed the nucleotides to get rid of the restriction sites while protecting the amino acid sequence. We looked through the codon bias property of E.coli and made the nucleotide changes accordingly.
