Embodiment 1

[0458] Example 1: Construction of XTEN_AD36 motif segment

[0459] The following examples describe the construction of a codon-optimized gene set encoding a 36 amino acid motif. In the first step, a stuffer vector pCW0359 is constructed based on the pET vector, which contains the T7 promoter. pCW0359 encodes a cellulose binding domain (CBD) and a TEV isoflurane recognition site, followed by a stuffer sequence. The stuffer sequence is flanked by BsaI, BbsI and KpnI sites. Insert the BsaI and BbsI sites so that they produce compatible overhangs after digestion. The stuffer sequence is followed by a truncated form of the GFP gene and a His tag. The stuffer sequence contains a stop codon, so E. coli cells carrying the stuffer plasmid pCW0359 form non-fluorescent colonies. The stuffer vector pCW0359 was digested with BsaI and KpnI to remove stuffer segments, and the resulting vector fragments were separated by agarose gel purification. The sequence was named XTEN_AD36, reflecting...

Embodiment 2

[0473] Example 2: Construction of XTEN_AE36 segment

[0474] A codon library encoding XTEN sequences of 36 amino acids in length was constructed. The XTEN sequence was named XTEN_AE36. Its segment has an amino acid sequence [X] 3 , Where X is a 12mer peptide, and the sequence is: GSPAGSPTSTEE (SEQ ID NO: 359), GSEPATSGSE TP (SEQ ID NO: 360), GTSESA TPESGP (SEQ ID NO: 361) or GTSTEPSEGSAP (SEQ ID NO: 362). The insert is obtained by annealing the following phosphorylated synthetic oligonucleotide pairs:

[0490] Example 3: Construction of XTEN_AF36 segment

[0491] A codon library encoding a sequence of 36 amino acids in length was constructed. This sequence was named XTEN_AF36. Its segment has an amino acid sequence [X] 3 , Where X is a 12mer peptide, and the sequence is: GSTSESPSGTAP (SEQ ID NO: 447), GTSTPESGSASP (SEQ ID NO: 448), GTSPSGESSTAP (SEQ ID NO: 449) or GSTSSTAESPGP (SEQ ID NO: 450). The insert is obtained by annealing the following phosphorylated synthetic oligonucleotide pairs:
