===Design Notes===
−
Through our work, we modeled Trim-21 with Dockerine and cohesin to know which one of them is more stable when it binds to Trim 21, we designed them by 5 tools (Robetta-Itasser-Alphafold-Modeller-TR Rosetta)  to reach the best model.

−
The results and literature showed that Trim21 binds to DocS is preferable to Coh2. Our top 2 models ranked 5 out of 6 according to our QA code.

Original Trim21 is expressed in humans. We acquired the sequence from iGEM team NUDT_2020 (BBa_K3396007)

Design Notes

An extra nucleotide was removed from the original part sequence on NUDT's part page, and the sequence was codon optimized for expression in E. coli BL21.
