Part:BBa_K3815000

Mxe GryA intein-PT-linker-ELK16 for peptide production

Fig1.The mechanism of ELK16

This part is for a new purification method, the ELK16 system. This part is composed of ELK16, Mxe GyrA intein, and PT linker. When this fused protein is produced, ELK16 self-assembles and precipitates. After that, taking this aggregate and adding DTT to it, the N terminal of Mxe GyrA intein is cut. Then, we can get the targeted protein. In this system, we do not have to need the expensive column or could save time removing tags.

Fusing the sequence of targeted protein to the N-terminus of intein, we can purify the peptide with ELK16 method. In our experiment, BBa_K3815002 could be successfully purified with ELK16 system.
