Chimerical gene (lysozyme and mlrA)

This part is the fusion of two basic parts in order to combine two separate function simultaneously: lyse cyanobacterial wall and degrade MCLR simultaneously.

Introduction

We have designed, based on our original goal, a basic part of chimeric lysozyme and mlrA gene with a linker sequence in between in order to create an enzyme that retain the both the function of lysing the cyanobacteria and denaturing their toxin MCLR. This part is intended to resolve the ultimate problem of cyanobacteria pollution. Therefore, the composite part contains our promoter, RBS, 6✖️His tag, lysozyme gene, a linker in between, mlrA gene and a terminator. During some of the experimental trials, we also managed to add a Sumo tag before the 6✖️His tag in order to increase the solubility of the enzyme.


Experience

Through Nested PCR, we are able to successfully infuse the lysozyme- mlrA gene into the PSB1C3 backbone. The linearized plasmid after the infusion is seen below on lane 2 and 8 of the gel. However, due to limited time, we were only able to focus on the function of lysozyme, which is part BBa_K2888002 and part BBa_K2888003.
