Design Notes

We began our design from the BBa_K1216001 part registered by the iGEM13_ETH_Zurich team (2). From the translated sequence of this part, we realized there were two stop codons at the begin of the sequence which led us to question how reliable the sequence was. To test reliability, we ran a BLAST analysis of the BBa_K1216001 and ran a Seaview alignment on the top 50 most similar sequences in E. coli. Based on this alignment we noticed that BBa_K1216001 had a N-terminus overhang that was not similar to other sequences. This led us to research alkaline phosphatase expressed primarily in E. coli. From this research we found the sequence created by Le Du, et al (3) which we then aligned with BBa_K1216001 to compare similarities.
