Nt-Barbie1-Cys

This part is the N-terminal of Spidroin Nt2RepCt (BBa_K5396002) fused to our Barbie1-Cys (BBa_K5396004).

Usage and Biology

Nt2RepCt

Spidroins are the primary proteins that compose spider silk. This part contains the N-terminal domain, which is involved in the initial formation of silk fibers and is crucial for the protein's solubility and stability, and is fused to the BaCBM2 protein, that has the ability to bind to plastics.

Barbie1-Cys

We utilized the BaCBM2 structural model generated by AlphaFold2 to conduct docking assays on six types of plastic: polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), nylon (NY), polyvinyl chloride (PVC), and polystyrene (PS). Using Gnina software, we assessed plastic affinity with relaxed parameters, followed by the elimination of overlaps through ChimeraX for visualization and sequence manipulation. A reverse folding process was applied to the docking outputs using LigandMPNN, filtering the original protein set to retain unique positions based on their scores. This approach generated a total of 36,000 sequences (6,000 per plastic type), leading to the identification of an optimized protein sequence named Barbie1, which has the increased ability to bind to plastics when compared to BaCBM2.

Part Generation

This Biobrick was created through PCR amplification and Gibson Assembly utilizing our composite parts:
