Dry Lab Characterization

Optimization

Firstly, we removed the last nucleotide in the original sequence from NUDT team 2020 to avoid the frame-shifting and preparing to codon optimization.

Also, we optimized the sequence to be expressed in E-coli BL21.

Modeling

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.

Source

original trim is expressed in human and we acquired the sequence from NUDT iGEM team 2020 BBa_K3396007
