Extracellular Electron Transport Module - Cloning - Golden Gate Assembly
Making a BioBrick of the mtrCAB operon is quite challenging. First of all, the coding sequence of mtrCAB contains several illegal restrictions sites. Secondly, we need to have the operon under the regulation of an adjusted T7 lac promoter, which was found to be the best promoter to express mtrCAB in E. coli [1]. To get rid of the illegal restriction sites as well as implementing the adjusted T7 lac promoter in our BioBrick BBa_K1316012 , we ended up having 5 pieces of DNA to be ligated into pSB1C3. To work efficiently, we used the LINK Golden Gate Assembly to clone BBa_K1316012 (see figure 1).
