Design Notes

The sequence of the subtilisin E gene from Bacillus subtilis was codon optimized for E. coli with the DNA and protein sequence analysis software "Geneious" and additionally with the "Codon Optimization Tool" from IDT. The sequence was partly ordered from IDT (BBa_K2020001 + BBa_B0010) and then cloned into BBa_J04500, a protein expression backbone which already carries the LacI promoter BBa_R0010 and the ribosome binding site BBa_B0034. Afterwards, a mutation in the active site of the enzyme was introduced by performing a site-directed mutagenesis. The codon TAT of tyrosine77 was substituted with TGG which codes for tryptophan.


Source

The sequences of the BioBrick parts were obtained through the Registry.
