Design Notes

For the constant expression of our gene, we had to use a constitutive promoter. We wanted our laccase to be active extracellularly so we needed to add a signal peptide either from the tat or sec pathway. We chose the tat pathway because we preferred our protein to exit the cell fully folded.


Source

The PgroES promoter and the LipA signal peptide originate from B.subtilis. The silA gene originates from Streptomyces ipomonae.
