Improvement

improved mlrA: BBa_K1378001 to BBa_K2888010

Description: Our composite part within prefix and suffix consists of the most commonly used promoter, RBS, 6x His tag and terminator, as well as our functional coding sequence --- mlrA gene. This composite part is assembled through Gibson Assembly; then, it is fused with linearized vector, pSB1C3 backbone, via infusion. Ultimately, we successfully extract plasmids which contain our target gene from transformed bacteria. Furthermore, we improved mlrA parts BBa_K1378001 by purposely adding 6x His tag into our sequence in order to improve the efficacy and efficiency of expression and purification; it will also strengthen effects of binding to Ni-NTA column, making it possible to immobilize proteins and lyse cyanobacteria repeatedly in our prototype device. In addition, we find that the attachment of SUMO protein can enhance the protein stability and expression system as an N-terminal fusion partner. And SUMO tag can be easily cleaved by a SUMO-specific protease in vitro during purification process.
