Cellulolytic complex [1]: His-Endo5a-GS-CBD

Our cellulolytic complex includes cellulase endo5a linked to CBD (cellulose binding domain) through a GS-linker and with a 6-histidine tag (His-tag) at the N-terminus.

The degrading power of our cellulolytic complex, as already mentioned in BBa_K3394000, is the cellulase enzyme Endo5a which breaks 1,4 beta glucose bonds. The other important component in our system is the CBD-cellulose binding domain. Its purpose is to bind the cellulose polymer to the displayed cellulolytic complex, thus enriching the cellulose surface with cellulose degrading bacteria, so the degradation will be more efficient.

In addition, we added a 6-histidine tag (His-tag) at the N-terminus of the sequence, to label our recombinant proteins in the purification assay.

In this design, the order of genes is: first the cellulase endo5a and then CBD. We made another design in which the gene order is different: first the CBD and then the cellulase endo5a (BBa_K3394005).
