Design Notes

The sequence has been optimized for expression in E. coli.

The vector used was pET-28a(+), which His-tag we planned to utilized when expressing our protein.

The sequence encodes the amino acid sequence "QPPP", which is very difficult for the ribosomes in E. coli to translate [1]. We did not do it, but for future projects we would recommend altering this part of the sequence, either by mutation or when ordering the sequence.

Primers for cloning into pET-28a(+) between restriction sites NdeI and EcoRI:
