Fabric Binding Domain 2 was fused downstream in the 5' end of the GFP CDS
FBD 2 was obtained by Phage display technique. We screened for small peptide ligands that selectively bind to the five different fabrics (cotton, wool, silk, linen, polyester) from a library of approximately 10^9 different peptides. These peptides were selected on the target by bio-panning, by which a pool of randomized peptides were screened based on the binding affinity to the target fabric. After three round of bio-panning, a consensus peptide sequence of “ADARYKS” was found to efficiently bind to different fabrics. The binding between the “ADARYKS”-harboring phage and fabrics's was confirmed by phage ELISA and the binding affinity was further characterized by fusing the FBDs to the N terminal of the GFP. A linker was introduced in the DNA sequence between FBD2 and the CDS of GFP.
His-tag is added in the C-terminal for protein purification
The sequence was codon optimized for E. coli and restriction sites for the restriction enzymes BpiI, BsaI and BsmBI were avoided. The sequence was confirmed by sequencing and no mutations were observed. The construction was done by Golden Gate technique using BsaI as restriction enzyme to obtain the desired cohesive ends.
