Design Notes

The domain 3 and the signal sequence are both the best conserved part from the attachment protein. Using a global protein alignment (Needleman-Wunsch alignment), using two or three sequence at one time, we were eventually able to determinate D3 from M13.

This is the complete amino acid sequence of M13 protein 3:

We choose to only keep the D3 of this protein:

We were able to found it because each domain is separated by a flexible sequence composed of Glycine and Serine [1]. Then we retrotranslate this sequence in a nucleotidic sequence and we used iDT to optimise this sequence for E.coli production.

Source

The initial sequence came from E.coli M13 filamentous phages. But we modified the sequence with iDT optimisation codon.
