His-tagged Cathepsin B
This Cathepsin B from Branchiostoma belcheri tsingtauense is originally a kind of hydrolase in lysosome.In our project,it has been used to biodegrade microcystin,a kind of biotoxin synthesized by cyanobacteria.
Usage and Biology
Our BioBrick encodes a kind of cathepsin from Branchiostoma diverticulum epithelial cells. Cathepsin is a class of proteins found in the cells of various animal tissues, especially lysosome parts. Based on the results of bioinformatics analysis, the protein we found out belongs to cathepsin B. In Branchiostoma diverticulum epithelial cells, we speculate this kind of protein plays an important role in degrading cyanobacteria and microcystin. In fact, according to our experimental result, Cathepsin B protein has high efficiency in degradation of microcystin LR. So we construct a composite part so that other teams can easily use it. This BioBrick can be implemented in any host expression system by cloning it into an appropriate vector.
