Part:BBa_K3505006

Tyr1-AIDAc Tyrosinase fused to membrane protein AIDAc. GB compatible B3-B5

Tyrosinase catalyzes the conversion of L-Tyrosine to L-Dopa and L-Dopa quinone. These derivatives can be detected electochemically, producing peak currents.[1]

Usage and Biology

AIDA is native E.coli outer membrane protein. AIDA's CDS constists of 3 parts: [2]

• A Signal Peptide that is cleaved in order the rest of the protein to be transported to the outer membrane.
• The AIDAc is the autotransporter with the transmembrane part.
• The passeger of AIDA which is the part that is on the exterior side.

We placed as passenger the Tyr1 gene coding to Rhizobium etli tyrosinase Because is the smallest of all tyrosinases (34kDa) and lack cysteines[3] compared to the melA tyrosinase BBa_K193600 used in iGEM before.

Design Notes

The coding sequence was domesticated . We removed BsmBI ,BsaI , BtgZI, BpiI sites in order to be compatible with GoldenBraid and MoClo. The sequence is present in pUPD2 BBa_K3505007as Level 0 and has overhangs compatible for GoldenBraid cloning. The CDS has position B3-B5.
