Design Notes
D3 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 domaine 3 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 used iDT to optimise this sequence for E.coli.
Source
The initial sequence came from E.coli M13 filamentous phages. But we modified the sequence with iDT optimisation codon.
