MAD7+recE/T+pEC+Ptac:MADE/TEtac
A recombinant plasmid with pEC-XK99E as the vector backbone, Ptac as the promoter of CRISPR-MAD7 and recE/T recombination system was constructed by using PCR and one-step cloning method. Under the action of Ptac promoter, CRISPR-MAD7 gene is expressed, and under the action of recE/T recombination system it can help the clipped gene to repair by homologous end recombination. Under the action of recE/T system can improve the editing efficiency of CRISPR-MAD7 system in Corynebacterium glutamicum.In the experimental process, we firstly transferred the constructed recombinant plasmid into E. coli by chemical transformation method to initially verify whether the recombinant plasmid is correct or not and amplify the recombinant plasmid. After extracting the recombinant plasmid from E. coli, the recombinant plasmid was transferred into Corynebacterium glutamicum by electroporation. This allowed the CRISPR-MAD7 system to be expressed in Corynebacterium glutamicum and gene editing to be performed.The results were observed and analyzed to determine whether the recombinant plasmid could be efficiently used in Corynebacterium glutamicum.
